Raman and infrared spectra of solid CH 2 CIF (Freon 31) were recorded in both the lattice and internal mode regions for samples at temperatures between 12 and 125 K. No evidence of any solid‐state phase transition was found, but some thin‐film samples deposited at low temperatures appear to exist in a metastable phase. Spectra of the stable phase are compatible with a non‐centrosymmetric unit cell containing four molecules. Lattice peaks are assigned on the basis of geometrical and intensity arguments.
