Abstract

The physisorption of CO on sodium chloride surfaces was probed by Fourier Transform Infrared Spectroscopy. Information concerning adsorption and desorption kinetics as well as the critical parameters which govern this reaction, such as binding energy and frequencies for molecule-substrate vibrations, has been obtained for CO adsorbed on NaCl films These paramenters are determined from a family of isotherms in the temperature range between -80K and 100K. Experiments have been extended to single crystal surfaces and a comparison between results on films and single crystal surfaces will be presented.
