EXTENDED DEADLINE: PHD POSITION IN DYNAMICS OF CHEMICAL REACTIONS
============================================================
Applications (deadline 1 September 2001) are invited for a PhD
position, available starting anytime between November 2001- April
2002, for theoretical research on the dynamics of chemical reactions,
at the Leiden Institute of Chemistry and Leiden Observatory of Leiden
University, The Netherlands. The research will be carried out in the
framework of a collaboration between the Theoretical Chemistry group
(Dr. G.J. Kroes and Dr. M.C. van Hemert) and the Astrochemistry group
(Prof. E.F. van Dishoeck), with funding from the Netherlands
Organization for Scientific Research, NWO. The project is described
below.
Applications should be sent by the November 1 deadline to:
Dr. G.J. Kroes, LIC, Gorlaeus Laboratories, P.O. Box 9502, 2300 RA
Leiden, The Netherlands.
FAX: +31-71-5274488, e-mail: [log in to unmask]
Candidates for the PhD position are asked to submit a CV, list of
grades, and arrange that two letters of reference be sent to G.J.
Kroes.

PROJECT: RADIATIVE ASSOCIATION (PhD student, 4 years)
In radiative association, two atoms or molecules combine to form a
single new molecule by releasing their excess energy through photons.
Radiative association is an essential process for the formation of
molecules at low pressures, such as found in interstellar clouds. An
important example within astrochemistry is the radiative association
of a positively charged carbon ion with molecular hydrogen. This
reaction is assumed to drive the entire carbon chemistry in
interstellar space. For the modelling of this chemistry, accurate
rate coefficients are required.
The time-dependent wave packet method will be used to study the
dynamics and determine rate coefficients for the above-mentioned
reaction. The necessary potential energy surfaces will be computed
using high level ab initio methods, as part of the project. The
central goal of the project is to determine the reaction mechanism,
i.e., the relative importance of purely electronic and vibronic
radiative transitions for the stabilization of the product molecule.
Other goals are to determine the lifetime of the collision complex,
the radiative lifetime of the complex, and the dependence of these
parameters on initial conditions.
Requirements: a Masters (or equivalent) degree in chemistry, physics,
astronomy, or numerical mathematics, with an interest in molecular
quantum mechanics. Experience with numerical methods and computer
programming will be helpful, but is not strictly necessary. For
