Structure and Dynamics in Metal-Containing Clusters

Authors: Michael A. Duncan; GEORGIA UNIV RESEARCH FOUNDATION INC ATHENS
Abstract:
Gas phase clusters were produced composed of a metal ion bound to one or more molecular "ligands" (e.g., water, nitrogen, acetylene, methanol, etc.). These gas phase complexes were studied with mass-selected laser photodissociation spectroscopy and laser photoelectron spectroscopy (ZEKE) . These studies determine the structures and energetics of these clusters and they probe the dynamics of nascent solvation processes. Other metal clusters and metal-organic complexes were produced in the gas phase and evaluated for their potential for isolation in macroscopic quantities. Mass spectrometry and laser photodissociation measurements were employed for metal carbides, metal-C60 complexes and complexes of metal with polyaromatic hydrocarbons. These studies provide detailed experimental data which can be compared to theory to improve the overall understanding of metal-molecular interactions.
