Depolarized Light Scattering

A low frequency study (Fabry–Perot) of the polarized and depolarized light scattering spectra of liquid pentachlorobiphenyl is presented from −54 to +150 °C.The relaxation time deduced from the depolarized spectra is measured as a function of temperature and compared with the time obtained by means of other techniques.The weak propagative depolarized doublet is studied at high viscosity, from −54 to +42 °C. The value of the shear rigidity modulus Gx is obtained almost up to the relaxation domain.The Brillouin polarized doublet is also analyzed in the full temperature range and the values of the compressional moduli are calculated.

Depolarized Light Scattering

A study of the depolarized light scattering spectra of high pressure supercooled pentachlorobiphenyl is presented. From the analysis of the propagative shear doublet, the infinite shear modulus Gx is measured over a large pressure range, at various temperatures, up to a pressure where the liquid is in a glassy state. Gx(P) is found to vary linearly at each temperature. From values of Gx (P = 0.1 MPa) together with those obtained in a previous paper at P = 0.1 MPa as a function of T, it is concluded that Gx(T) is linear over 70 °C, contrary to what is generally obtained in most of the supercooled molecular liquids.
