Infrared Spectroscopic Study of C12/02 Co-Adsorption on Al(111)

Abstract

Fourier-transform infrared reflection-absorption spectroscopy (FT- IRRARS) has been used to observe the effects of C12(02) pre-adsorption on the vibrational modes of 0 (C1) formed by exposure of A1 (111) to 02 (C12). On clean A1, C1 at surface sites gives rise to a stretching mode at 745-760/cm (depending on coverage), and a second band at 820/cm is tentatively assigned to subsurface C1. Exposure to 02 either before or after C12 leads ultimately to a single broad band at a frequency intermediate to those for exposure of the clean surface to either C12 or 02. The results indicate strong coupling between A1-0 and A1-C1 modes and suggest that the two species are intimately mixed during co- adsorption. Chlorine, Oxygen.
