Temperature Dependence of Acoustically Induced Optical Anisotropy in Pure Liquids

The temperature variation of the optical anisotropy induced in several viscous liquids by acoustic waves was studied over a temperature range of approximately 270°–350°K. The results were obtained from performing a polarization analysis on the Fraunhofer optical diffraction pattern produced by the acoustic waves. Values of theoretical parameters defined from the theory of Peterlin for acoustically induced optical anisotropy in pure liquids were calculated from this data.
