摘要：

An intense background of isotropic scattering has been observed in the Brillouin spectrum of glycerine. Its breadth varies inversely as the viscosity or structural relaxation time, which changes by a factor of about 50 in the temperature range studied, 23 to 91°C. Thus the background is attributed to a known structural relaxation process in glycerine. These results suggest that the appearance of a broad background of isotropic scattering from liquids is a general phenomenon occuring whenever a structural or a thermal relaxation is present. © 1968 The American Physical Society.
