Summary on Grant Application Form |
|
Radical intermediates are at the heart of most gas-phase reaction mechanisms. These include key technological and environmental processes such as combustion, plasmas, and atmospheric chemistry. The aims of this proposal are to improve fundamental understanding and provide practically useful kinetic data on the transfer of energy and polarisation in the collisions of two of the most widely occurring radicals, CH and OH. The collision partners will be the majority stable molecules also typically present during combustion.Individual elementary steps will be isolated by laser-photolytic generation of the radicals in the presence of selected collision partners. Measured quantities will include rate constants for rotationally, vibrationally and electronically inelastic collisions; branching ratios over the available product states; and the extent to which the transfer of population is accompanied by retention of the plane of rotation. They will be deduced from complementary laser-spectroscopic techniques. The established method of dispersed laser-induced fluorescence (LIF) will be combined in a novel way with single-colour polarisation spectroscopy (PS), and most originally with a new application of two-colour, pulsed-laser polarisation labelling spectroscopy (PLS).
