Raman spectra of the layered compound, antimony triiodide are reported for samples at ambient temperature and at pressures up to 16 GPa. Changes in the number of observed peaks and their wavenumbers, relative intensities and spectral linewidths are discussed. Evidence for reversible crystallographic phase transitions at 0.3, 0.8 and 4.9 GPa is presented. Samples subjected to pressures greater than 8.3 GPa undergo an irreversible transition to a new phase which is stable up to 16 GPa. On release to ambient conditions from pressures between 8.3 and 16 GPa, SbI 3 adopts a structure which is stable but different to that originally observed. © 1988 John Wiley & Sons, Ltd.
