The Development of Laser Analytical Methods for the Characterization of Solid/Liquid and Solid/High Pressure Gas Interfaces.
Abstract
This report summarizes research in two areas: laser induced thermal desorption at solid/UHV interfaces, and surface enhanced optical spectroscopy at solid/liquid, solid/gas and solid/UHV interfaces. The major accomplishment in the first area was the development of a pulsed laser induced thermal description technique for probing surface desorption and diffusion. In the second area, an apparatus has been constructed which enables the measurement of the surface enhanced Raman and other surface optical spectra in UHV. In addition, surface enhanced spectra were measured for a number of adsorbate/substrate combinations in electrochemical cells, and the theory of surface enhancement effects was elucidated. Originator-supplied keywords include: pulsed laser thermal induced desorption, carbon monoxide, Cu(100), surface diffusion, surface enhanced Raman spectroscopy, surface enhanced Resonance Raman spectroscopy, fluorescence quenching, electromagnetic theory, time dependent Hartree Fock.
