Abstract : The research supported by this grant centers on the spectroscopy and dynamics of a variety of transient species including transition states, clusters, and free radicals. These species lie at the heart of many chemical processes, and our experiments have provided unprecedented insight into their nature. The novel feature of this program is that negative ion spectroscopy is used as the basic experimental tool in all of these experiments, because in many cases negative ions provide the only way to generate the transient species of interest in a reasonably well-defined manner. The projects described fall into three categories: (a) spectroscopy of the transition state and reactive intermediates for neutral, bimolecular reactions, (b) the spectroscopy and electron detachment dynamics of carbon cluster anions, and (c) studies of size-selected, weakly bound anion and neutral clusters.
