Vibrational spectra and the force field of ethylidyne tricobalt nonacarbonyl: analogies with spectra from the chemisorption of ethylene upon the Pt (111) crystal face

Abstract

A detailed vibrational analysis is reported for CH3CCo3(CO)9 and for its deuterated analogue, and assignments have been confirmed by means of an approximate normal-coordinate analysis. Some significant revisions of an earlier assignment have been made. Comparison of these spectra with those obtained by electron energy-loss spectroscopy of a species resulting from the chemisorption of acetylene and ethylene on Pt (111) above 300 K supports the identification of the latter as containing a C·CH3 group. The two most probable alternatives are a CH3CHPt2 species or CH3CPt3+adsorbed hydrogen atoms.
