Abstract : The research supported by this AFOSR grant has involved a multi-technique (NMR, ESR, laser flash photolysis, single photon counting, photoluminescence, tailor-made syntheses, computer simulation) approach to address problems concerning the structure and dynamics of transient high energy intermediates. These techniques have been employed to investigate the behavior of these intermediates when the latter are confined to the interfacial regions of restricted reaction spaces such as micelles, zeolites, cyclodextrins, water soluble polymers, and silica. Unique information has been obtained concerning the nature of interactions between the transients as substrates bound to receptors by non-covalent bonding. This information, in turn, has been exploited to investigate situations for which the transients display extraordinary dynamic properties such as reactivity which is controlled by the application of very weak applied magnetic fields.
