Abstract
The polarized Raman spectra of oriented single crystals of glycerol (normal and 0‐deuterated) have been recorded from 120 to 273 K; the spectra of super‐cooled and glassy glycerol have been obtained within the same range of temperature. The behavior of the νOH, νOD and γOH bands of the crystal is analyzed according to the theory of anharmonic multiphonon processes. The interactions involving one or two low‐frequency (optical and acoustical) phonons appear to be chiefly responsible for the damping of these modes. The thermal shift of the bands is mainly assigned to the effect of volume variation; the corresponding Gruneisen mode parameters are calculated.
