The chemistry of chromyl fluoride. IV. Raman spectrum of CrO2F2 in the solid and liquid phases

Raman spectra are reported for liquid and solid chromyl fluoride. Nine Raman lines, of which four are polarized, are observed for CrO2F2(l) and assigned to a monomeric structure possessing C2v symmetry. Some reassignments for previously reported gas phase infrared bands are suggested based on the new Raman data. The symmetric Cr–F stretching vibration at 708 cm−1 in CrO2F2(l) disappears in the spectrum of the solid phase material, which has a new Raman line at 540 cm−1 characteristic of extensive fluorine bridge bonding.
