✦ Synopsis

The laser Raman spectra of chloroform, carbon tetnchloride, trans-1,2dichloroethylene, tctrachlorocthylene. tetramethytethylene. wt.-butyl cyanide, benzene and cyclohcxane adsorbed on silica surfaces have been remrded. The Raman shifts of the adsorbed molecules do not significantly dcviatc from those of the liquids and the Raman selection rules arc not viotted by the adsorption The relative intensities of the Raman bands of adsorbed species arc distinct from those of the liquids. Rusons for these intensity changes on adsorption arc discusscd.?hc surfaa electric field is found to be an important factor. . The laser Raman spectra of a variety of unsaturated

## Abstract Raman spectral results for CO adsorbed at high pressures on Ni(100), Ni(110) and Ni(111) are presented. The bands near 2020 cm^−1^ due to chemisorbed CO are discussed in relation to site of adsorption and surface cleanliness. Raman spectra of temperature and pressure‐dependent CO adsorp
