Team Leader: Professor V. E. Bondybey
Organisational Experience: Coordinator of a previous EC environment research project (contract EVSV-CT93-0344 with the Universities of Dublin and East Anglia); member of the Editorial Board of Physical Chemistry Chemical Physics (1999-present), Molecular Physics (2000-present), Chemical Physics Letters (1980-2000) and the Journal of Chemical Physics ( 1984-1986).
Research Experience: More than 250 publications on spectroscopy of free radicals and reactive intermediates, molecular ions, photochemistry, nonradiative transitions, laser driven processes, and the structure and reactivity of cluster ions.
Network Role: To perform fundamental studies of cluster ion reactions of relevance to atmospheric chemistry in collaboration with the Lisbon and Salisbury groups. Regular contacts will be maintained with these and other participants.
Staff Involved: Professor V. E. Bondybey (4mm/year), Dr. M. K. Beyer (5mm/year), U. Achatz (5mm/year), M. Lorenz (5mm/year), Dr. A. Smith-Gicklhorn (5mm/year).
Research Links: The informal links which already exist with the other participants in the proposed Network will be strengthened by regular meetings. Research links with other group members have been established at a meeting of the Network in Orsay in May 1998.
Laboratory: The group has four state-of the-art experimental spectrometers, i.e. a FT-ICR mass spectrometer for cluster ions, a high-resolution ZEKE spectrometer for molecular clusters, a matrix isolation spectrometer for reactive intermediates, and a cavity ringdown laser absorption spectrometer for metal complexes and small metal clusters. High-level ab initio structure codes are also available, notably: GAUSSIAN and MOLPRO.

Research Role: It is proposed to use fundamental studies of large size-selected water clusters and a variety of hydrated ion species as model systems for investigating reactions of relevance to atmospheric chemistry. A high resolution FT-ICR mass spectrometer has been modified for these studies by addition of a supersonic cluster beam source. The reactions chosen for study will address the roles played by sulphur oxides, ozone, and CFCs in the atmosphere. Reactions will also be studied on clusters based on Rh and Pt, to overlap with the surface work performed in Lisbon.
