Abstract
The Raman spectra of Cr(CO)6 have been measured in an Argon matrix at 13 K and in the solid state at 292 and 13 K. As expected only the A1g, Eg and F2g modes were observed in the matrix spectra. The ν4(Eg) mode was observed split into a polarized and a depolarized component. This indicated a lowering of the symmetry from Oh to D4h or one of its subgroups. Depolarization ratios obtained in the matrix were close to values obtainable in liquids. In the low temperature solid state spectra all thirteen fundamental modes as well as several overtones and combination bands were observed. The six modes ν5(F1g) (inactive), ν6(F1u), ν7(F1u), ν8(F1u), ν12(F2u) (inactive) and ν13(F2u) (inactive), which were previously inferred from overtones and combinations, were observed for the first time.Keywords
