Although it proved possible in recent years to improve greatly the understanding of unimolecular reactions, much less is known about the true nature of termolecular recombinations and dissociation reactions 2 A M A2 M. The objective of the present investigation was to obtain accurate rate data for such reactive systems and to use these data in order to verify or discard existing theories of dissociation-recombination. An important accomplishment involved the development of a high temperature flash photolysis technique fo studying Br and I atom recombination from room temperature up to 1300K in a single experiment. In order to reduce experimental data to accurate rate constants, various thermal effects, which interfered with measurements, were studied. Furthermore, recombination was also studied over an appreciable pressure range of third body, M. A variety of third bodies were used and their properties, if related to recombination reaction, were studied. Author
