Abstract : In this project, we have carried out a collaborative experimental and theoretical study of a number of elementary collisional processes involving small molecular free radicals of importance in combustion and in the decomposition of propellants. These have involved chemical reactions and photodissociation, as well as nonreactive collision-induced rotational and electronic transitions. In addition, we have obtained information on the non-bonding interactions between a free radical and a rare gas partner through analysis of the electronic spectrum of the van der Waals complex of these species. The close interaction of our experimental and theoretical groups has allowed much greater insights to be obtained on the dynamics of these collisional processes than would have been obtained by the effort of these groups working independently.
