Raman spectroscopy on metal and oxide surfaces
- Univ. of Arizona, Tucson, AZ (United States)
Raman spectroscopy has received increasing attention as a surface analysis tool as developments in instrumentation, particularly the introduction of charge-coupled device (CCD) detectors, have been achieved. Work in this laboratory focuses on the application of surface Raman spectroscopy to the study of interfacial chemistry of interest in several areas including electrochemistry, organized molecular assemblies on surfaces, and chromatographic systems. Strategies have been developed which have enabled investigation of interfacial chemistries at metal and oxide surfaces not heretofore amenable to study by Raman spectroscopy. Selected examples which demonstrate the power of surface Raman spectroscopy for the elucidation of this chemistry at the molecular level will be presented in this talk. Specific examples to be discussed include recent studies on in-situ and emersed electrochemical interfaces, self-assembled monolayers on single crystal substrates, and chemically-modified stationary phases on silica surfaces. Spectral regions containing molecular information not readily ascertained from other techniques will be highlighted.
