Cluster Model Studies of Condensed Phase Phenomena at Well-Defined Conditions


EMSL Project ID
44676

Abstract

This program is aimed at obtaining a microscopic understanding of solution chemistry and condensed phase phenomena using gas phase clusters as model systems.Our current focus is on the microsolvation of complex anions that are important in solution chemistry and environments. Our primary experimental technique is photoelectron spectroscopy coupled with electrospray ionization, which is used to produce complex anions, including multiply-charged anions, and solvated clusters from solution samples. With the new development of a cold and temperature-controlled ion trap, ionic clusters can be probed at cold and well-defined temperatures. A central theme of this research program lies at obtaining a molecular-level understanding of environmental materials and solution chemistry, which is important to address issues related to waste storage, subsurface and atmospheric contaminant transport, and other primary DOE missions.
