IN-SITU INFRARED-SPECTROSCOPY AT ELECTROCHEMICAL INTERFACES

An insight into the in situ FTIR spectroscopy method as applied in Ele ctrochemistry is given. The particular aspects inherent to the electro chemical method are described in a concise form. Selected examples cov er the results of about the last 8 years, on a variety of systems incl uding carbon monoxide, small organic molecules and double-layer compon ents (hydrogen, anions and water). The experimental data refer mostly to adsorption on well-defined single-crystal surfaces. Analogies and d ifferences with data from the metal/gas interface are discussed.
