Abstract

Thin films of carbon or metal are vacuum-deposited on KRS-5 (TIBr-Til) internal reflection elements. Infrared internal reflection spectrometry can then be employed to observe chemical reactions taking place at the resulting metal or carbon surface. This method is applicable to redox reactions of and at the surface, adsorption of organic molecules from solution, etc. Examples of the applications of this technique are presented, including the solution oxidation of carbon films by K2K20a/ H2S04, the adsorption of bovine albumin on a carbon surface, and the air oxidation of a copper film.
