Notes:
The low frequency Raman spectra of CF3OF (gas, liquid), CF3OCI (liquid), CF3OOH (gas, liquid), CF3OOD (liquid), CF3OOF (gas, liquid) and CF3OOCI (liquid) have been recorded below 300 cm-1. The spectra have been assigned and the CF3 torsional modes were observed for all of these compounds in the liquid state. The assigned frequencies for the liquids and the calculated barriers for the vapor state are: CF3OF, ντ = 144 cm-1, V3 = 4.64 kcal mol-1; CF3OCI, ντ = 122 cm-1, V3 = 4.6 kcal mol-1; CF3OOH, ντ = 155 cm-1, V3 = 6.0 kcal mol-1; CF3OOF, ντ = 78 cm-1, V3 = 2.9 kcal mol-1; and CF3OOCI, ντ = 80 cm-1, V3 = 3.7 kcal mol-1. The assignments are discussed and the barriers are compared to the corresponding quantities in some similar molecules.
