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 about 1300 members.

Postdoctoral in Chemical Mapping of Cell and Virus Surfaces via Scanning Near Field Optical Microscopy

Scanning near field optical microscopy (SNOM) gives images with a resolution less than the wavelength of light by scanning an sharpened optical fibre probe over a surface. By working in the near field the resolution is only limited by the size of the near field probe and resolution of between 10 - 80 nm can be obtained. We have constructed a unique reflection mode SNOM (Rev.Sci.Instrum 68,1448,1997) capable of working in liquids and studying hydrated biological specimens, and have shown recently that it is possible to identify the position of monoclonal antibodies upon a virus surface. We are seeking a suitably qualified person to extend these studies and make considerable modifications to the instrument in order to improve its resolution and efficiency. The ultimate aim of the project is to map binding sites on virus and cell surfaces using fluorescently labelled antibodies.

A postdoctoral position for up to three years is available in the research groups of Dr David Klenerman and Dr Trevor Rayment in the Department of Chemistry, Cambridge University, to begin as soon as possible. Applicants should have a strong experimental background with experience in optics, laser spectrosocopy or scanning probe methods. A background in molecular biology is not required since we collaborate with groups at the Laboratory of Molecular Biology, MRC Cambridge, and the Nuffield Department of Clinical Medicine Oxford, who will supply the samples used in these experiments however it is important that the person appointed is keen to learn about this area.

Photodissociation Spectroscopy and Dynamics in Mass-Selected Metal Ion Complexes

Weakly bound metal ion complexes (M⁺ -Rx, where M=Mg, Ca, Ti, etc. and R=Ar, CO₂, H₂ O, N₂, C₂ H₂, etc.) are investigated as models for metal cation solvation, metal-ligand bonding and metal ion atmospheric chemistry. Complexes are produced and cooled in a pulsed nozzle laser vaporization cluster source in a two-chamber molecular beam machine. The species produced are mass-analyzed and mass-selected with a reflectron time-of-flight mass spectrometer. Electronic states, vibrational frequencies and structures of these complexes are investigated with photodissociation spectroscopy. Complexes absorb near metal atomic transitions to populate bound excited molecular states, and then dissociation occurs following the absorption of one or more additional photons. New experiments use an infrared OPO to probe ligand-based vibrational overtones. These experiments determine the structure of metal ion complexes and their bond energies and follow the development of these properties as a function of cluster size. Instrumentation for this project includes the pulsed molecular beam machine with reflectron TOF mass spectrometer, a XeCl excimer laser for the cluster source (Lambda Physik EMG 101), an ArF excimer laser for photoionization (Lumonics PM-840), a YAG-pumped dye laser (Spectra-Physics GCR-170 with Lambda Physik ScanMate 2E and doubler unit) and a new YAG-pumped OPO/OPA system (Continuum 9010 YAG with "SunLite" OPO and doubler unit). Data collection with a digital oscilloscope (LeCroy 9410A) and laser scanning are controlled with a Pentium PC.

Fock's representation of momentum space hydrogenic orbitals in terms of harmonics on the hypersphere S³ of a four dimensional space is extended to classify alternative bases. These orbitals are of interest for Sturmian expansions of use in atomic and molecular structure calculations and for the description of atoms in fields. Due to the correspondence between the S³ manifold and the SU(2) group new sum rules are established which are of relevance for the connection, not only among hydrogen atom orbitals in different bases, but also among usual vector coupling coefficients and rotation matrix elements.

It is shown that the standard binning method utilized in the classical study of scattering processes dealing with more than three atoms, is not appropriate when the total energy disposal in the products is too low for the classical and quantum densities of vibrational states to be equal. Two simple semiclassical corrections are proposed.

Energy distribution functions for the products in two classes of three- atom unimolecular reactions are derived which are much more realistic than the prior distributions of Levine and Bernstein without being more complicated. In a first step, we deal with light-atom emissions gover- ned by short-range forces and in a second step, with processes governed by long-range forces. Comparison is done with experimental results or results of simulations.

For some complex-forming processes governed by long-range forces, the kinematics are such that the recoil energy distribution may be very excited, despite the absence of exit-barrier, i.e., of repulsion forces between nascent fragments.

The key problem of exit-channel effects in unimolecular reactions, which make Transition State Theory generally unsuitable for the calculation of product state distributions, is analysed in some details in the triatomic case, for a total angular momentum equal to zero.

The recoil energy distributions in the products of the title reactions are derived within the framework of Phase Space Theory (PST). The strong fluctuations observed experimentally, in contrast with the smooth character of the bell-shaped distributions usually observed in bimolecular complex-forming processes, are analysed.

Angular momentum algebra is generalized to compute matrix elements of the Hamiltonian operator parametrically in the hyperradius. Advantages are that no integrals are required and the construction of the kinetic energy matrix is simple and universal: salient features are the block tridiagonal structure, a number of symmetry properties and sparseness.

Scientific Programme: Chemical reactive and photofragmentation processes will be treated from the molecular point of view, with the aim of providing information on the role of microscopic properties in determining the relationship between structure and chemical as well as photo-reactivity. Laboratory quantum state resolved experiments as well as semi- classical and quantal theory of state-to-state reactions will be lectured upon. Applications are abundantly found in atmospheric sciences: the complex ozone (photo)- chemistry and the ozone hole; the role of photodissociation in protecting the earth from of the UV radiations; the impact of cosmic rays on the composition and temperature of the earth atmosphere. A link will be made towards atmospheric science by discussing rate constant determination and the importance of large chemical-box models of the atmosphere.

This conference incorporates the 4th European Conference on Gas-Surface Dynamics and the 3rd European Conference on Lasers in Surface Science. Chairman: Mats Persson (Göteborg), Vice Chairman: Christof Wöll (Bochum)

A central issue in surface science is the identification and description on an atomic level of elementary dynamical processes underlying various surface phenomena in nature. Some typical examples of such phenomena are heterogeneous catalysis, oxidation, friction and wear, and atmospheric reactions on ice surfaces. The study of such processes, which is the theme of this meeting, is now possible thanks to recent advances in our knowledge of the geometric and electronic structure of adsorbates on surfaces and to recent developments of experimental and theoretical approaches to study the dynamics at surfaces. Spectacular examples of these approaches, which also form the basis for this meeting, include on the experimental side state-resolved molecular beam experiments, atomic and molecular manipulation by scanning tunneling microscope, femtosecond laser techniques, and on the theoretical side the developments of reliable total energy calculational schemes based on density functional theory and classical and quantum molecular dynamics calculations.

The meeting will have sessions of talks on: Gas-surface scattering; Reaction dynamics; Photo dynamics and chemistry; Potential energy surfaces; Chemistry on the nanoscale; Cluster deposition, growth and diffusion; Surface reactions and catalysis; New frontiers. Time will be available for presentations to be selected from the participant's abstracts. Poster sessions will be included to which all participants may contribute. There will be a special prize for the best student poster presentation. Applications from young investigators are encouraged and funds are available to subsidize the selected applicants.

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.

Bretton Hall, University of Leeds, 5-7 July 1999

Faraday Discussion No 113 will be held at Bretton Hall, University of Leeds, 5-7 July 1999 on the theme of "Stereochemistry and Control in Molecular Reaction Dynamics". The Discussion will focus on comparing frequency, temporal and phase control strategies to probe elementary chemical processes. Further details are available at

Experimental and theoretical papers will be particularly welcome in the following areas:

* High resolution studies (both frequency and time resolved) of molecular photodissociation of photoinitiated processes

* Control of reactivity via collision energy, selective vibration of reagents, or reagent alignment

* Demonstrations of active or coherent control of chemical processes

At this time we are seeking Titles and Abstracts of about 300 words. The DEADLINE for submission of these proposed contributions is FRIDAY 29 MAY 1998. They should be sent to Dr. BJ Whitaker, School of Chemistry, University of Leeds, LS2 9JT and may be in any form - manuscript, fax, whatever but electronic attachments will be particularly cherished. Papers should be concerned with new, unpublished work. The full proceedings of the Discussion will be published late in 1999, but papers accepted for discussion will be circulated to all participants before the meeting in July 1999. Those unfamiliar with the unique format of Faraday Discussions can obtain more information from the URL above.

To the memory of

(1941 - 1998)

A meeting will be held on the afternoon of Monday 14th September 1998 in the Chemistry Department, Manchester University. This meeting will include recollections and scientific contributions related to Roger's work and provide the opportunity for Roger's former students, colleagues, collaborators and friends to commemorate his scientific achievements and remember his life.

The meeting will be preceded by a buffet lunch and will be attended by members of the family. It is also planned to launch an appeal to establish a prize or scholarship in Roger's memory at this time.
