Infrared spectra and molecular orbital model for carbon monoxide adsorbed on metals
by Blyholder, George D.; Allen, Marvin Carrol
Infrared spectra are presented in the CO stretching region for CO adsorbed on V, Cr, Mn, and Co. Band maxima for the two main bands of each metal are located at V, 1940 and 1890 cm-1; Cr, 1940 and 1880 cm-1(sh); Mn, 1950 and 1890 cm-1; and Co, 2000 and 1880 cm-1. These data together with previously presented data for Fe, Ni, and Cu allow comparisons across the first transition series from V to Cu. A molecular orbital model for the pi-electron system of CO adsorbed on a cluster of metal atoms successfully accounts for the shifts in position of the two principal bands as the metal is varied across the series.
