Raman and infrared spectra of solid bromotrifluoromethane

Abstract

AbstractRaman and infrared spectra of solid bromotrifluoromethane were recorded in both the internal and lattice mode regions at temperatures between 12 K and the melting point. No evidence of a solid‐state phase transition was found. Lattice peaks were assigned on the basis of geometrical and intensity arguments, and splittings of internal modes were interpreted in terms of isotopic or crystal field effects. A non‐centrosymmetric unit cell containing four molecules was shown to be compatible with the observed spectra.
