Abstract
An earlier method of calculating CO stretching force fields for mono- and bi-nuclear metal carbonyl compounds, with the help of i.r. intensities, has been extended to incorporate Raman data. The Raman solution spectrum of Hg[Co(CO)4]2 in the CO-stretching region has been obtained, including the measurement of intensities and depolarization ratios, and the present treatment has been applied to this case. Compared with previous studies, a reassignment of two Raman bands seems necessary. The experimental evidence suggests that Raman intensities may be more directly applicable than corresponding i.r. data to the evaluation of carbonyl-stretching force constants.Keywords
