Offices Held in Professional Organizations

Elected to the Executive Committee of the American Chemical Society's Division of Physical Chemistry in August, 1994; term ends in August of 1997.
Served on the Executive Committee of the Western Spectroscopy Association (WSA) from 1991-1994. In 1991, served as Secretary/Registrar for the WSA annual conference in Asilomar, California, which ran from January 29-31, 1992. Over 150 participants attended this conference.

Current Research

Our work during the last several years and at the present is divided into three areas: studies of the electronic structure of the solvated products resulting from the photodissociation of transition metal carbonyl complexes in solution, investigations of the multiphoton dissociation dynamics of gas phase arene chromium tricarbonyl complexes, and use of lanthanide ions as luminescence probes to investigate the coordination of metals in proteins. Our investigations of solvated chromium pentacarbonyl species have successfully utilized time-resolved resonance Raman spectroscopy to measure several of the vibrational frequencies and probe the excited electronic states of these important species. The studies of multiphoton dissociation dynamics have been directed at using atomic fluorescence yields to measure the nascent electronic state distribution of Cr atoms produced in the multiphoton dissociation of a series of n-alkyl substituted arene chromium tricarbonyls. Recently, laser-induced fluorescence measurements of relative populations of non-emitting states revealed a parity selectivity in the dissociation process. Finally, for each of the past five years I have shared a senior thesis student with Arthur Glasfeld, a biochemist at Reed. We have assembled an instrument for measuring the laser-induced fluorescence lifetimes of lanthanide ions in solution, and we recently used Europium (III) as a luminescence probe to investigate the nature of one of the metal binding sites in D-xylose isomerase. This study confirmed that the metal binding capacity of the Mg-2 site is not dramatically altered in a mutant form of this enzyme, and that the coordination geometry has been maintained; this information was important to using this mutant to explore the role of the metal site in substrate binding and isomerization.
