technical note:
This version of the MDN 85 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 July 1995 had about 1000 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 a new 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:

Relaxation Process of Charge Transfer in C_60: A Normal Mode Analysis To appear in Physics Letters A P. Zhang, X. F. Zong, X. Sun, Thomas F. George* and Lakshmi N. Pandey Office of the Chancellor / Departments of Chemistry and Physics & Astronomy,University of Wisconsin-Stevens Point Stevens Point, WI 54481-3897
It is found that after one electron is transferred to C_60, only a few normal modes with even parity need be invoked, where the Ag mode exchanges the energy with the system nearly harmonically, and the Hg mode dominates the relaxation process.
Fluctuations of Light Scattered by Fractal Clusters To appear in the Journal of the Optical Society of America A Vadim A. Markel, Vladimir M. Shalaev, Evgeni Y. Poliakov and Thomas F. George* Office of the Chancellor / Departments of Chemistry and Physics & Astronomy University of Wisconsin-Stevens Point, Stevens Point, WI 54481-3897, tgeorge@uwsp.edu
It is shown that for a wide range of wavelengths and angles, relative fluctuations in the scattered intensity are very close to unity and do not depend on the number of monomers N in fractal clusters, whereas it is proportional to the inverse square root of N for trivial clusters.
Dynamical Process of Exciton Trapping in Fullerene To appear in Synthetic Metals G. P. Zhang, H. Zhao, X. Sun, Thomas F. George* and Lakshmi N. Pandey Office of the Chancellor / Departments of Chemistry and Physics & Astronomy, University of Wisconsin-Stevens Point, Stevens Point, WI 54481-3897, tgeorge@uwsp.edu
Due to the electron-lattice interaction, photoexcitation in C_60 induces bond distortion, which forms a self-trapping exciton and reduces the symmetry of C_60 from Ih to D5d, where the relaxation time for the exciton trapping is about 90 fs, which is four times faster than that of charge transfer in C_60.

Neutral-neutral reactions in the interstellar medium I: formation of carbon hydride radicals via reaction of carbon atoms with unsaturated hydrocarbons Astrophys. J. R.I. Kaiser, D. Stranges, Y. T. Lee, and A. G. Suits Department of Chemistry, University of California and Chemical Sciences Division, Lawrence Berkeley National Laboratory, Berkeley, California, 94720.
The reactions of atomic carbon in its ^3P_j electronic ground state with acetylene C_2H_2 (1), methylacetylene, CH_3CCH (2), ethylene, C_2H_4 (3), and propylene, C_3H_6 (4), were investigated at relative collision energies between 8.8 and 45 kJ/mol in crossed beam experiments to elucidate the reaction products and chemical dynamics of atom-neutral encounters relevant to the formation of carbon bearing molecules in the interstellar medium (ISM). Reactive scattering signal was found at m/e = 37, 51, 39, and 53, i.e. C_3H (1), as well as the hitherto unobserved interstellar radicals C_4H_3 (2), C_3H_3 (3), and C_4H_5 (4). All reactions proceed on the triplet surface via addition of the carbon atom to form propendiylidene and cyclopropenylidene, C_3H_2 (1), 1-methylpropendiylidene, C_4H_4 (2), cyclopropylidene, C_3H_4 (3), as well as methylcyclopropylidene, C_4H_6 (4). The initial collision complexes undergo hydrogen migration (1/2) or ring opening (3/4) and decompose via C-H-bond rupture to l/c-C_3H (1), n-C_4H_3 (2), propargyl (3), and methylpropargyl (4). The explicit identification of the carbon-hydrogen exchange channel under single collision conditions identifies this class of reaction as a potential pathway to carbon-bearing species in the ISM. Our findings strongly demand the incorporation of distinct structural isomers in prospective chemical models of interstellar clouds, hot cores, and circumstellar envelopes around carbon stars.

We present ionization rates for a 1D H_2 at different frequencies and intensities of short intense electromagnetic pulses by solving exactly the time-dependent Schrodinger equation as a function of internuclear distance.Anomalously high ionizatin rates are found at large critical distances,akin to similar results found previously in the one electron molecule H_2^+.Idependent one-electrond and simultaneous two-electron ionizations are identified from the numerical simulations.

The derivation of the metric tensor provides the corresponding classical kinetic energy functional. A novel feature is a parametrization of inertia tensor components by independent angular variables, which also span configurations of opposite chirality: it avoids the problem of interdependence of the range of variables.

6. 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.
