Environmental concerns such as the air quality in industrial regions and inner cities, are attracting considerable governmental and public attention, and significant efforts are being made to improve standards. One major research area involves the interaction of man-made pollutants (e.g. hydrocarbon diesel exhaust and sulphur containing materials) with solar radiation. Amongst the fundamental data required top solve these environmental problems is the dependence of molecular reaction mechanisms and rate constants on energy. Expressed in more basic terms, information is needed about molecular excitation and decay dynamics, and the flow of energy between reactants and products. The present proposal concerns a study of the photoionisation and decay dynamics associated with photon-molecule collisions. Synchrotron radiation will be used to create a molecular ion in a well-defined excited electronic state. This ion may decay by fluorescence or fragmentation. If the ion decays by fluorescence a monochromator will be used to disperse and analyse this fluorescence at rotational state resolution. This will allow information to be obtained on the exchange of energy and angular momentum between the photoelectron and the ion core. Alternatively, if the excited ion decays by fragmentation, the product ion intensities will be determined as a function of parent ion internal energy. Rate constants for the various fragmentation pathways will be obtained. Studentship, held jointly by Heriot-Watt University and Daresbury Laboratory and the collaboration with Belfast University forms another link with students. In addition to the development of scientific and technological skills, the students will benefit through the interaction with a wide multi-disciplinary scientific community.
