Studies of Transition States and Cluster-Induced Reactivity Via Negative Ion Photoelectron Spectroscopy

摘要

Research during the last three years has focused on using negative ion photoelectron (PE) spectroscopy and zero electron kinetic energy (ZEKE) spectroscopy to probe the effects of clustering on the energetics, spectroscopy, and dynamics of ions and transition states, and to investigate the ground and excited electronic states of reactive free radicals. We have also developed a new spectroscopic method in which stimulated Raman pumping combined with PE spectroscopy is used to measure vibrational frequencies in negative ions. Results are summarized in more detail below.
