Low temperature Raman measurements of carbon monoxide adsorbed on nickel at high pressures

Abstract

Abstract The Raman spectra of carbon monoxide adsorbed on Raney nickel and on supported SiO 2 are measured at high pressures and low temperatures with a rotating cell. In addition to the vibrational bands of adsorbed Ni(CO) 4 , we find three band systems of CO stretching vibrations at high wavenumbers and several bands at low wavenumbers. The CO stretching vibrations agree with infrared spectra.
