Raman and infrared spectra of crystalline tin tetrabromide at temperatures between 20 K and the melting point, 304 K, are reported. No evidence of any solid‐state phase transition was found. Splittings of the four molecular modes are discussed in terms of crystal field effects and isotopic species. All twelve Raman and five of the nine infrared‐active lattice modes, predicted on the basis of a group theoretical analysis, have been observed. Since these peaks lie within a relatively narrow frequency range, and since the molecules are located on general sites in the unit cell, mixing between modes is likely to be considerable.
