MESSAGE FROM THE EDITORS

Molecular Dynamics News has now published more than 100 issues since Dick Zare and Raphi Levine started the newsletter in 1982. We have witnessed great progress in the field during this time because of advances in experimental techniques as well as extraordinary improvements in the speed and capabilities of computers that has been exploited by new theoretical and computational approaches. Now the advances in computational capability have opened a whole branch of Molecular Dynamics dealing with simulations even in liquid and solids, which has grown up outside the scope of the newsletter. Even the avenues for the dissemination of timely scientific information has progressed enormously, and we have exploited that. Now most of our subscribers get the issue by email or read it on the web. For a few years we also have, on the initiative of Jeremy Hutson, a complementary email list. We take the occasion of celebrating the 100th issue to thank all those who have helped by subscribing and submitting contributions. We are confident that you will continue to contribute, so as we feel encouraged to continue publishing the newsletter into the next millenium.

We are also sorry for the production problems that have interrupted timely publication of this newsletter for the past two issues. We believe that these problems have now been resolved. This issue contains all information that would have been published in April and June except for Conferences that have already occurred and were previously announced in MDN and expired job postings.

ELECTRONIC DELIVERY OF MDN

We offer to our subscribers several possibilities for electronic delivery of MDN:

1. Electronic mail to subscribers
In this case subscribers tell us if they want the newsletter automatically sent to them by electronic mail. Subscribers may specify whether they want a raw LaTeX source file or a Postscript file.

Alternatively the files can be downloaded for local viewing or printing. Subscribers choosing this delivery option will receive an email announcement when a new issue is posted.

We periodically update the home page, and you can find links to Molecular Dynamics News subscribers' home pages at our WWW site. We will add a link to your home page if you send us the address by email or with the subscription form on the cover page of this issue. There is also a list of MDN subscribers that is linked to their email addresses. We appreciate electronic mail with updated email and home page addresses. Please send your email messages to MDN@CHEMISTRY.UCSC.EDU We continue to send hardcopy newsletters by mail to subscribers who request this form of delivery.

The MDN e-mail list continues, as detailed below

MOLECULAR DYNAMICS NEWS EMAIL LIST

All members of the chemical physics community are invited to join the (free) ``molecular-dynamics-news'' email list. The ``molecular dynamics'' in the title is to be interpreted as meaning ``dynamical processes in molecules'' rather than ``classical simulations of molecular motion''. The list can be used to distribute details of conferences, vacant academic and postdoctoral positions, changes of address and other news in the Molecular Dynamics field. It also serves as an archive of up-to-date email addresses for people in the field. The list was created by Jeremy Hutson in June 1993 and has now more than 1300 members.

Instead of being maintained manually, the list is operated by a system called ``mailbase''. People can join or leave the list simply by sending messages to the mailbase program, without the list owner needing to do anything. To join the email list, send a message to the Internet address mailbase@mailbase.ac.uk containing a line of the form:

join molecular-dynamics-news John F Kennedy

You do not need to tell the program your email address, as it picks it up from the message header. It does needs to be told your real name, so that it can maintain a useful list of email addresses.

When you join, you will receive some introductory information on how to circulate information to the molecular-dynamics-news list, and on the mailbase system itself.

If you would like a list of the current members, send a message containing the line

review molecular-dynamics-news

to the address mailbase@mailbase.ac.uk

Note that messages distributed via the e-mail list are not normally printed in the newsletter, unless the Editors receive an explicit request to do so.

There is also a spectroscopy email list. To join this email list, send a message to the Internet address mailbase@mailbase.ac.uk containing a line of the form:

POSTDOCTORAL POSITION, University of Notre Dame

Applications are invited for a POSTDOCTORAL POSITION in experimental gas/surface reaction dynamics at the University of Notre Dame. Reactions between incident ions and surface adsorbates are explored under UHV conditions. Ions are accelerated to hyperthermal energies (5-300 eV) and collide with well-characterized single-crystal surfaces. A differentially-pumped QMS is used to detect scattered products with angular-, mass-, and energy-resolution. In addition, TPD, AES, XPS, and Kelvin Probe measurements are employed to monitor surface modifications following prolonged ion beam exposures. The mechanisms for charge transfer, dissociation, and atom abstraction reactions are probed by measuring how the reaction probability and product distributions depend on the collision energy, angle-of-incidence, and the surface adsorbate structure. Candidates with previous experience in charged particle optics and/or surface science techniques are especially encouraged to apply. Applicants should send a curriculum vitae and arrange for two letters of recommendation to be sent to:

POSTDOCTORAL POSITION, Columbia University

A postdoctoral position in the area of state-to-state dynamics of chemical reactions is available immediately in the laboratory of Professor James J. Valentini. The emphasis of the project is on the elucidation of the influence of "many-body" effects-those features that distinguish reactions in which one or both reactants are polyatomic from the prototype atom + diatom reactions. Current target systems are atom + polyatom reactions like H + CH₄ and H + CHCl₃ as well as more complex systems. The experiments rely on REMPI measurements-Doppler-resolved and distance-of flight/position-resolved-to map the energy distributions of both reaction products. Stimulated Raman excitation methods are used to vibrationally prepare the reactant molecule, and laser photolysis creates the reactant atom. Related studies focus on reactions in molecular clusters, where the "many-body" effects are solvation-like. The experiments are complemented by computational simulations of the dynamics of the reactions on realistic model potential energy surfaces as an aid to interpreting the experimental results.

Interested applicants should contact Professor Valentini via email, fax, or mail, and arrange to have two letters of recommendation sent to him. The position will remain open until a suitable candidate is found.

Please quote reference A170D. Completed forms, accompanied by a full curriculum vitae and the names of two academic referees, must be received by the Personnel Office by 13 August 1999.

The Research Projects and Job Descriptions

Position 1 is for a Senior Research Assistant to work with Prof. Jeremy Hutson and Dr. Pavel Soldan on an EPSRC-funded research project entitled "Long-range interactions involving atomic and molecular ions". The main thrust of the project is to use the spectra of near-dissociation states of ionic complexes such as Ne₂⁺, Ar₂⁺, NeN⁺ and HeH₂⁺, which have recently been measured by Carrington and coworkers (Southampton), to learn about the potential energy surfaces for ionic interactions and the dynamics of near-dissociation states. We have used similar spectra of HeAr⁺ and HeKr⁺ to develop reliable potential surfaces (or, equivalently, sets of potential curves and the couplings between them), and have carried out high-level ab initio calculations on He-H₂⁺ designed to assist in assigning its spectra. See J. Chem. Phys. 102, 2379 (195) and 105, 8602 (196) and Chem. Phys. Lett. 260, 395 (1996) for more details.

The current project is to extend these studies to: polyatomic systems; homonuclear systems, where the g/u symmetry of the states may be broken sufficiently close to dissociation; and triplet states

An exciting recent development is the possibility of "morphing" ab initio potential energy surfaces to fit experimental data. The original potentials need not be of ßpectroscopic" quality, but are "bent and stretched" to bring them into agreement with experiment. The morphing procedure offers the prospect of obtaining potentials of ßpectroscopic" quality for much larger systems than previously.

Position 2 has a wider remit. Jeremy Hutson is currently Head of the Chemistry Department, and the Department has agreed to fund a postdoctoral Research Assistant to underpin his group's research activities during his term as Chairman. The Senior Research Assistant will be expected to: Undertake research on intermolecular forces, especially on extending the "morphing" approach described above; Organise group meetings; and assist with the day-to-day supervision (and recruitment) of research students and undergraduate project students;

Assist with research grant management.

There will also be opportunities for the successful applicant to participate in making research grant proposals and to undertake some teaching duties.

Further information on the research group and the University of Durham is available at http://www.dur.ac.uk/~dch0www/Staff/jmh

For both positions, the successful applicant will require either a Ph. D. or postdoctoral research experience in theoretical chemistry or chemical physics.

The salary will be on the standard RA 1A scale for research staff in UK Universities. The scale runs from 16,286 - 24,479 pounds per annum, according to age and experience, but the funding available is such that these appointments will have to be made near the lower end of the scale.

Other theoretical chemistry research groups at the University of Durham include those of: Mark R. Wilson (atomistic modelling of molecular materials), David J. Tozer (fundamental studies of density-functional theory), Stuart C. Althorpe (theory of chemical reaction dynamics).

There are also close links with the Durham Physics Department, including David Flower (molecular collisions), Robert Potvliege (multiphoton processes), Charles Adams (laser cooling and trapping), Brian Bransden (electron and positron collisions with molecules), Stewart Clark (materials modelling).

Note that Jeremy Hutson will be in the USA for almost all the period from now to the closing date, and may not be able to answer email promptly.

POSTDOCTORAL POSITION, UNIVERSITY OF CALIFORNIA, DAVIS

A postdoctoral position is currently available to study the photodissociation of cometary molecules using velocity imaging. Vacuum ultraviolet light is produced by four wave mixing of ultraviolet laser light. This light is used to dissociate molecules in the VUV region that are thought to be responsible for the formation of free radicals and products in comets and planetary atmospheres. The heavy and light products are then analyzed with a second VUV laser directly in either a one-photon process or using a multiphoton scheme. The ions are imaged onto a multichannel plate detector, which produces electrons that are accelerated onto a phosphor screen. The resulting image is recorded with a camera and analyzed to determine the velocity and angular distributions.

The laboratory is well equipped for this study with two 30Hz Nd-Yag laser, 4 dye lasers, 5 excimer lasers, computers, electronics, an imaging apparatus along with a variety of other experimental systems. Experience with ultra high vacuum systems, Nd-Yag lasers and dye lasers, and mass spectrometry is desired but not essential.

The University of California, Davis is located 60 mi. east of Berkeley, 75 east of San Francisco, and 17 mi. west of Sacramento. It is also only 125 mi. to the ski country around Lake Tahoe.

The position is for one year and is renewable for a second year. Please send a short CV along with the names of three references to: William M. Jackson, Chemistry Department, University of California, 1-Sheilds Ave., Davis, CA 95616, USA

POSTDOCTORAL POSITION, SRI INTERNATIONAL

The Physics and Atmospheric Chemistry (PAC) Unit of the Molecular Physics Laboratory (MPL) is searching for well-qualified candidates for a post-doctoral position in experimental physical chemistry. The work involves collision energy transfer studies of excited states of molecular oxygen and nitric oxide, typically by means of pump-and-probe ionization techniques, under the supervision of Dr. Richard Copeland and Dr. Tom Slanger. These studies are directed towards an improved understanding of upper atmospheric processes. In recent years, the collisional energy transfer rates and pathways of all the oxygen electronic states lying below the first dissociation limit have been studied, even including the quintet state that had long been hypothesized as a possible atmospheric precursor. Nitric oxide is an important trace gas in the upper atmospheres of both the terrestrial and Venusian atmospheres, and its two metastables are to be investigated as part of a program to study auroral processes. These investigations connect to field observations, as we are learning to take advantage of the fact that large telescopes around the world routinely generate spectra of the terrestrial night airglow that are far better in terms of resolution, sensitivity, and spectral coverage than has previously been available.

SRI International is a not-for-profit contract research organization, located in Menlo Park, California, in the San Francisco Bay region, and is one of the largest such establishments in the world. Many areas of research are represented by the investigations carried out at SRI, including chemistry, physics, engineering, life sciences, computer sciences, education, and a variety of other disciplines. MPL has an international reputation for creative and innovative research in atmospheric studies, combustion processes, surface science, plasma research, and molecular beam research. Within MPL, the members of the PAC unit have been active for many years in studying the chemistry and physics of the atmosphere, with Drs. Copeland and Slanger's emphasis on the processes that occur in the 80-120 km night airglow region. There has been close coupling between the laboratory kinetics studies that this group carries out, and the results of optical emission studies by field observers.

We expect the candidate to have experience in the operation and maintenance of pulsed laser systems. Other qualifications include a Ph.D. degree in chemistry or physics, and beyond laboratory abilities, effective technical writing is an important attribute for the position, as well as an ability to make oral presentations. Appointment is typically for a minimum of one year, with a second year normally being available upon mutual agreement. The salary will depend on the experience of the candidate.

A CV, three letters of recommendation, and a one page "research interests" summary should be sent to:

The dynamics of this reaction has been studied using the QCT method on three different triatomic LEPS PES model. On the basis of the experimental vibration al distributions and QCT results, it is suggested that the NO(v'=16, 17) + NO (v'=0) state-specific reaction channel is not majoritary. However, is about this channel that most of the reaction dynamics information is available. A quite good description of the dynamics of this specific channel has been obtained. We have also shown that for a very exoergic reaction without a stron g kinematic constraint , like the one under consideration, the vector relation j'=a l, with a being a constant, can occur if the PES has no barrier or a negligible one along the minimum energy path and is highly isotropic.

An ab initio study of the ground PES of this reaction has been performed using the second and fourth order Moller Plesset ab initio methods with a large basis set. From the ab initio data a triatomic analytical PES has been derived. This PES has been employed to study the kinetics and dynamics of this reaction. The ab initio points have also been used directly to calculate the VTST rate constant considering all the atoms of the system. The best VTST methods used lead to a good agreement with the experimental rate constant for 1000-2500 K, but the QCT ones are about one third the experimental ones for 1500-2500 K. The cold QCT OH(v=0) rotational distribution obtained is in good agreement with experiments, and the very small QCT OH(v=1) population obtained is consistent with the measurements. The triatomic PES model may be used in dynamics studies under conditions where the methyl group motions are not stron gly coupled to the motions leading to reaction.

It is found that this highly-efficient isomerization is closely related to the highly-selective optical transitions, and the dipole-allowed transitions occur selectively around the dihedral angles of 60 degrees and 120 degrees, where the system is able to undergo cis or trans isomerization.

Due to the one-dimensional characteristic, the excitation of an electron in polymers is self-trapped, and two excitons can be combined to form a biexciton. By solving the dynamic equations, the relaxation process of this combination is investigated, where it is found that the relaxation time is about 160 fs.

The two most dominant Hg modes are identified which play an essential role in the dynamical properties of C₆₀, which is consistent with the experimental results, which clarifies the previous theoretical ambiguity showing that the electron-phonon coupling constant is basically the same for different modes.

From exact non-Born-Oppenheimer simulations of dissociative-ionization of H₂⁺ in an intense(I > 10¹⁴ W/cm²),ultrashort(t < 5fs) laser pulse we show that it is possible to measure directly from the kinetic energy of coulomb exploded protons the probability distribution of any initial vibrational state or wavepacket. The theory of the inversion method is presented and its application to Laser Coulomb Explosion Imaging, LCEI, of time dependent wave packets is demonstrated through numerical simulations.

Exact numerrical solutions opf the time-dependent Schroedinger equation of one and two electron molecular ions in short(t < 50fs) intense(I > 10¹⁴W/cm2) laser pulses show that molecular ionization rates exhibit unusually large values at critical configurations, interfragment distances Rc and internal angles phic. Large charge resonance radiative couplings are shown to be responsible for the large ionization rates called Charge Resonance ionization, CREI. Exact non-Born-Oppenheimer calculations on molecular dissociative ionization of H₂⁺ confirm the role of CREI as a üniversal" phenomenon in recent Coulomb Explosion experiments.

Ionic fragmentation of MMA has been observed using either Laser MPI (2.35eV) or Synchrotron PI (from 12.1eV to 287.9eV), coupled to a time-of-flight technique The fragmentation pattern remains the same in both PI cases. MPI causes extensive fragmentation, the parent ion can not be observed and C⁺ becomes the most intens
