(USSR) 4, 499 (1941) (In English) en_US dc.description Author Institution: Department of Physics, University of California en_US dc.description.abstract Effects of viscosity and temperature on the scattering caused by fluctuations of optical anisotropy in liquid carbon disulfide and in liquid mixtures of carbon disulfide and carbon tetrachloride has been investigated by observing scattered light near the $4880{\AA}$ line from an $Ar^{+}$ laser. In pure $CS_{2}$ at $293^{\circ}K$, the line shape close to the incident frequency is Lorentzian with a half-width of $5.6 cm^{-1}$. The half-width has been found to be proportional to the temperature divided by the viscosity of the liquid whereas the total scattered intensity appears to be constant as a function of temperature. From the half-widths of the scattered radiation, relaxation times for the reorientation of molecules in an a.c. electromagnetic field have been calculated. These half-width measurements agree with the simple picture of $Debye^{1}$ for orientational scattering in an electromagnetic field. In addition the measured line shapes and polarization effects are in agreement with the predictions of $Leontovich.^{2}$ en_US dc.format.extent 147663 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title SCATTERING OF LIGHT BY FLUCTUATIONS OF ANISOTROPY IN LIQUID CARBON DISULFIDE en_US dc.type article en_US
