technical note:

This version of the MDN 89 was transferred into the html format by using TeX2RTF version 1.0 (by Julian Smart). It was "brushed up" a little (well ...) by hand editing the file, but there are still some problems with special characters, sub- and superscripts. A "^" in the text indicates, that the next character is supposed to be a superscript and a "_" indicates a subscript. Greek characters are spelled out. For the moment there are no internal links in this page, so you have to read it the old fashioned, linear way.
Sorry for the inconvenience.

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 in January 1997 has about 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:

NORTHWESTERN UNIVERSITY, DEPARTMENT OF CHEMISTRY

I am looking for a theory postdoc to help me with a new project that falls at the interface of optical physics and materials chemistry. This is a collaborative project which involves my colleague Mark Ratner as well as several experimentalists (R. Van Duyne, J. Hupp, W. DeHeer, M. Jarrold, C. Mirkin, J. Ketterson), and the primary activity for this position is to develop and apply theories which are capable of describing the optical properties, both linear and nonlinear, of assemblies of clusters or nanoparticles. This would be an ideal position for someone with interests in light scattering theory and/or nonlinear optics, but I am willing to be flexible. There is also a connection with magnetic nanoparticles, so background in the magnetic properties of materials is another possibility. Some of our work would build on past studies in my lab of absorption spectra and Raman intensities using converged electrodynamics calculations. References to this past work are: W. -H. Yang, G. C. Schatz and R. P. Van Duyne, JCP 103, 869 (1995); W. -H. Yang, J. Hulteen, G. C. Schatz and R. P. Van Duyne, JCP 104, 4313 (1996) and A. C. R. Pipino, R. P. Van Duyne and G. C. Schatz, Phys. Rev.

ACADEMIA SINICA, INSTITUTE OF ATOMIC AND MOLECULAR SCIENCES

A post-doctoral position is open in the group of Prof. Y.T. Lee at the Institute of Molecular Sciences (IAMS) of Academia Sinica, Taiwan, ROC, in the field of chemical reaction dynamics. Over the past three years, we have employed the crossed molecular beams technique to elucidate the chemical dynamics, energetics, and reaction products of C(3Pj) reactions with unsaturated hydrocarbons and hydrogen sulfide in extraterrestrial environments . Our investigations revealed that these atom - neutral reactions established a versatile route to form carbon-containing radicals in the interstellar medium (dark clouds and outflow of dying carbon stars), in atmospheres of Jupiter, Saturn and its moon Titan, Uranus, as well as Neptune, and after impact of comet Shoemaker-Levy 9 into the Jovian atmosphere. The prime directive of the new candidate is to extend these studies to explore the chemical dynamics of reactions involving boron and silicon atoms with closed shell molecules employing the crossed molecular beams technique. Energetic candidates should send inquiries prior to September 1, 1997 to:

The size dependence of the internal conversion efficiency for the optically excited electronic S_2-state in benzene(NH_3)n clusters has been studied. The analysis o pump-probe experiments with 160 fs laser pulses reveals a significant enhancement of the S_2 to S_1 conversion probability with the number n of ammonia molecules in the cluster. In contrast, the total deactivation rate of the S_2-state by internal conversion of about 10^-13 s^-1 is nearly independent of the cluster size.

The morphology of several dielectrics (a-SiO_2, CaF_2 and BaF_2) irradiated by laser light at a wavelength of 790 nm for different pulse width (between 200 fs and 5 ps) and fluences near the single shot damage threshold has been investigated by using the complementary techniques of electron microscopy and atomic force microscopy. Differences can be observed which we relate to the mechanisms and dynamics of defect production in these wide bands gap materials.

The infrared spectroscopy of thin films of fullerenes containing approximately 30% endohedral Li@C_60 has been investigated. A strong signal is observed corresponding to the vibrational motion of the Li inside the fullerene cage. In addition, a number of modes corresponding to the reaction products of the films with air can be observed. The films can be dissolved in CS_2 allowing the chromatographic separation of the pure endohedral material.

Laser processing of sapphire using a Ti:Saph laser at 790 nm and 395 and pulse widths varying between 0.2 and 5ps is reported. A clear improvement in quality is demonstrated for multi-shot processing with sub-ps laser pulses. For fluences between 3 and 12 J/cm^2 two ablation phases were observed, in agreement with previous work from Tam et al. using 30 ps, 266 nm laser pulsed [1].

We have recorded the dispersed laser induced fluorescence spectrum of gas phase C_60 ablated from a rotating copper cylinder by 308 nm radiation from a XeCl excimer laser. At vibrational energies below 7000 cm^-1 the spectrum consists of three progressions of either odd quanta in the lowest frequency t_2u mode, with the lowest h_u and g_u modes as additional origins or the third hg mode with two quanta of the lowest gu mode and the combination h_u(1) + g_u(1) as the additional origins. At higher vibrational energies, the observed bands become more complex, and have yet to be analysed.

To study the stereodynamics of atom diatom reactions we apply the formalism developed by Aquilanti et al (J. Phys. Chem. 95, 8184 (1991)). As a case study the prototype Li + HF -> LiF + H reaction at zero total angular momentum J is considered. For this reaction we calculated the scattering S^J-matrix in the standard mid lj> representation and transformed it into a stereodirected representation. In this way it is possible to investigate the effect on the reaction probability of the orientation of the target HF molecule with respect to Li attack. In the investigated collision energy range (0.45-0.54 eV) propensity is found for Li attack on the side of H-atom.

2. 1997 Conference on the Dynamics of Molecular Collisions
Gull Lake, Minnesota USA, July 20-25, 1997

The Dynamics of Molecular Collisions (DMC) Conference is the major conference in the United States on the topic of molecular collisions and related phenomena. This conference was begun as a Gordon Conference in 1965, and has been held every two years since then. In recent years it has been held at major resorts around the country, most recently (1995) at the Asilomar Conference Center in Pacific Grove, California (Dan Neumark, chair). The Asilomar Meeting attracted over 300 participants from around the world, with 23 invited talks and about 235 poster talks. The 1997 Conference will be held at Cragun's Resort on Gull Lake near Brainerd Minnesota. This resort is located in the central lakes district of Minnesota in a region of beautiful pine forests and many thousands of lakes. The conference was last held at Cragun's in 1983. Since then the resort has been substantially improved, with increased space for poster and oral talks, modernized sleeping rooms, and many new recreational facilities including an indoor sports center. In addition, Cragun's has its own beach, sail and motor boats, tennis courts and golf course, and nearby are hiking and biking trails and other attractions. Cragun's is about a 2.5 hour drive from the Minneapolis airport; we plan to arrange for ground transportation to and from the conference. Alternatively, if you fly on Northwest airlines to Minneapolis, the extra fare to fly to the Brainerd airport is about $40 roundtrip. The scientific program will be international and will cover all aspects of molecular collisions, including reactive and nonreactive collisions, and related photochemistry and surface processes. Both experimental and theoretical topics will be included. Suggestions for specific areas or speakers are welcome and should be addressed to the conference chair. The meeting will follow a Gordon Conference format, i.e., morning and evening sessions from Monday morning to Friday noon, with afternoons free for informal discussions, recreation, and relaxation. Time will be set aside for formal presentation of poster papers and long discussion periods after invited talks. The conference program committee consists of chair George C. Schatz, Northwestern University and vice-chair James J. Valentini, Columbia University. Further details will be announced in the fall of 1996. This conference has generally included at least one representative of almost every major experimental and theoretical group studying molecular collision dynamics in the United States, as well as a very good representation from foreign groups. We hope that you will be able to attend the 1997 meeting and urge you to mark off the week of July 20-25 on your calendar now.

8. Faraday Division, Royal Society of Chemistry - Faraday Discussion 108 "The Dynamics of Electronically-Excited States in Gaseous, Cluster and Condensed Media"
University of Sussex, UK, 15-17 December 1997 Organising Committee: G S Beddard, R J Donovan, R Grice, J M Hutson, A Orr-Ewing, B Soep, A J Stace, J C Whitehead (Chairman)

There are now a wide range of experiments being performed that can study various aspects of the dynamics of electronically-excited states in gaseous, cluster and condensed phases. The aim of the Discussion will be to explore the similarities and differences beetween these processes in the different media focusing on the effect of the medium. The processes involved include energy transfer processes, chemical reaction, decomposition to neutral and ionic fragments, proton and electron transfer. Contributions are invited for consideration by the Organising Committee. Titles and abstracts should be submitted by 20th DECEMBER 1996 to Dr J C Whitehead, Chemistry Department, Manchester University, Manchester, M13 9PL (j.c.whitehead@man.ac.uk). Full papers for publication in the Faraday General Discussion 108 will be required by August 1997. Further details about the Discussion can be obtained from Ms Shazia Riaz, riazs@rsc.org.

9. Faraday Division, Royal Society of Chemistry - Faraday Discussion 110 " CHEMICAL REACTION THEORY"
University of St Andrews, Scotland, 1-3 July 1998

CALL FOR ABSTRACTS

This will be the first Faraday Discussion devoted purely to the theory of chemical reactions, one of the most rapidly developing areas of theoretical chemistry. Predictions on the dynamics of the reactions of small molecules can now be as reliable as experimental measurements and the accuracy of calculations on more complicated problems ranging from reactions of organic molecules to reactions on surfaces and in solution is improving at a very fast pace.

The committee specially welcomes theoretical or computational papers in the following areas:

* ab initio calculation of accurate potential energy surfaces for chemical reactions
* scattering theory for the accurate treatment of the reactions of small molecules
* extension of theory to dynamics and kinetics of larger molecules
* reactions of molecules on solid surfaces and in solution

The papers chosen for the Discussion will be concerned with theory or calculations that can be tested by comparison with experiment. St Andrews University on the east coast of Scotland is over 500 years old and is a beautiful place to hold the meeting (especially in July). The accommodation facilities there are excellent. There are good connections to St Andrews from the international airport at Glasgow and also from Edinburgh. Contributions are invited for consideration by the Organising Committee. Titles and abstracts of about 300 words should be submitted no later than 1 JUNE 1997 to Professor D C Clary, Department of Chemistry, University College London, London WC1H OAJ (email: d.c.clary@ucl.ac.uk). Full papers for publication in the Faraday General Discussion 110 volume will be required by February 1998. Organising Committee: D C Clary (Chairman), J N L Connor, I H Hillier, S Holloway, W C Mackrodt , D E Manolopoulos, M A Robb

10. 15th International Symposium on Gas Kinetics

The 15th International Symposium on Gas Kinetics will be held in Bilbao, Spain, during the week 12-19th September 1998. Further details from Prof. F. Castano (qfpcaalf@lgdx02.lg.ehu.es)
