Dr. David F. Kelley is supported by a grant from The                         Experimental Physical Chemistry Program to perform                              time-resolved studies of reaction intermediates which are                       isolated in low temperature Argon matrices.  This research will                 provide a more fundamental understanding of the physical                        process of chemical reaction.                                                                                                                                      Two areas of research will be explored: 1) studies of                        photo-induced bimolecular cycloaddition reactions of aromatics                  and aromatic olefins, and 2) studies of intermolecular excited                  state proton transfer.  In both cases the species to be studied                 will be formed in a molecular jet expansion and trapped in a                    matrix of condensed argon carrier gas.  Reaction intermediates                  will be studied by picosecond emission, two color laser induced                 fluorescence and absorption spectroscopies.  A variety of                       allowed ?2+2! and ?4+4! addition reactions will be studied with                 reactants chosen to facilitate unambiguous assignment of the                    intermediate transient spectra.  The studies of intermolecular                  excited state proton transfer reactions will elucidate the                      effects of solvation on proton transfer rates.  For these                       experiments proton donors will include phenol, alpha- and                       beta-napthols, and their nitro-substituted derivatives, while                   solvents will include water, ammonia and alcohols.
