Raman and far‐infrared spectra of solid CBr 4 at temperatures between 20 K and the melting point, 365 K, have been recorded. Low‐temperature results are compared with earlier data and with the predictions of a group theoretical analysis based on the known crystal structure. Isotopic and crystal field effects are distinguished. The number of Raman peaks, especially in the lattice and v 3 regions, is compatible with a large unit cell. Certain features are interpreted with the help of recent spectra and calculations on solid SnBr 4 , Which has a similar unit cell.
