Photodissociation and spectroscopy of gas phase bimetallic clusters. Final report, September 15, 1990--September 14, 1993

摘要

Focus is the study of gas phase metal clusters to evaluate their potential to model fundamental interactions on metal surfaces. Chemical bonding between component atoms in metal clusters and physisorption on cluster surfaces are studied. Electronic spectra, vibrational frequencies, and bond dissociation energies are measured for both neutral and ionized clusters using laser/mass spectrometry. Interest is on bimetallic cluster systems and how they compare to pure metal clusters. The following were studied: Bi/Cr, Bi/Fe, Pb/Sb, Ag(sub 2)-rare gas, Ag-Al, Ag-K, Ag-Na, Ag-Li, and Ag(sub 3).
