Spectroscopy of Anion and Transition States Using Stimulated Raman Pumping

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 Rg(n)X(-), (b) PES of I2(-)Ar(n) and I2(-) (CO2)n, 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 I(3), CH3O, and NCN, and (d) time-resolved studies of excited state dynamics in I(-)(H2O)(n) clusters using femtosecond photoelectron spectroscopy (FPES).
