Abstract:

Some recent applications of surface vibrational spectroscopies to electrochemical and related interfacial systems are illustrated by means of studies undertaken in the authors laboratory. The utility of infrared reflection-absorption spectroscopy IRAS for linking the structural behavior of absorbates on ordered metal surfaces in electrochemical and vacuum environments is discussed with reference to a vacuum-based study of COD2O coadsorption on Pt111. The use of atomic-resolution scanning tunneling microscopy in tandem with in-situ IRAS for electrochemical adlayer structural elucidation is noted. Some virtues of surface-enhanced Raman spectroscopy SERs for examining metal- adsorbate vibrations on transition metals in both electrochemical and high- pressure gas-phase systems are also briefly illustrated, specifically for rhodium surface oxidation.
