Notes:
Polarization data for the Raman-active k = 0 phonons of single crystals of α-P4S3 have been measured at 10 K and at high resolution. Of the 24 external and 60 internal phonons expected for the D2h factor group of α-P4S3 we have observed 16 external and 38 internal phonons. The effect of the layer lattice has been proposed to explain the absence of some expected phonon structure. The present work together with an earlier study of the pressure and temperature dependence of the Raman-active phonons have enabled the 4A1, A2 and 5E internal molecular modes to be assigned. The resulting normal coordinates give good fits for the Raman-active bands of the heavy isotope P4 32S2 34S and for the mixed chalcogen species P4S3 - xSex.
