Abstract:

During the last grant period, we have used negative ion photoelectron spectroscopy PES and ZEKE spectroscopy to probe the spectroscopy and dynamics of negatively-charged and neutral species. Specific areas include a ZEKE spectroscopy of diatomic rare gas halides RgX-and clusters of the form RgnX-, b PES of I2-Arn and I2- CO2n, in which the effects of solvation on a molecular as opposed to atomic ion are probed, c PES as a probe of neutral radicals and reactive intermediates, specifically I3, CH3O, and NCN, and d time-resolved studies of excited state dynamics in I-H2On clusters using femtosecond photoelectron spectroscopy FPES.
