Principal Research Interests
We use anion photoelectron spectroscopy and flow tube ion-molecule chemistry to study the gas phase structures and reactivities of metals and metal-ligand complexes. The electron affinities, electronic state energies and vibrational frequencies measured in these experiments provide insight into the chemical bonding and energetics of the neutral and negatively charged metal dimers, clusters and organometallic complexes. We use density functional theory to calculate the structures, vibrational properties and energies of different spin states and isomers to aid in spectroscopic assignments. The photoelectron data can provide benchmarks for computational studies, and can contribute to an improved understanding of the evolution of metallic properties with increasing particle size and the chemical reactivities of metal catalysts.
