My research interests are directed towards understanding the structure and bonding of single molecules containing transition metal atoms using
both spectroscopic and computational methods. The types of experiments in which I am interested include:
1) spectroscopic studies of traditional metal-ligand complexes in condensed phases using standard techniques (e.g. UV-Vis and infrared) and resonance Raman. A recent example of
this type of study is the UV-vis and resonance Raman characterization of the blue-colored aqueous complex formed by Cu2+ and pyrazole (C3N2H4).
2) spectroscopic studies of exotic transition metal species, either in the gas phase or trapped in rare gas cryomatrices. I plan to construct a cryomatrix isolation/resonance Raman
system to conduct rare gas matrix experiments, and to continue collaboration with Doreen Leopold at the University of Minnesota to study gas phase systems via anion photoelectron
spectroscopy. Systems studied by these methods are generally bare metal clusters (e.g. Al3), metal atoms/clusters which do not have a full ligand sphere (e.g. products of the reaction
between gas phase metal atoms and ethylene), and/or open-shell metal systems.
3) computational characterization of systems observed experimentally. For example, computational results suggest that the Cu-pyrazole system mentioned above has the copper
ion in a nearly square planar ligand environment (see below). Other ongoing computational projects include identification of YCmHn- reaction products formed by
reacting ethylene and Y, and collaborative work with the Leopold group on the structure of Cr3- and Cr3.
