In dealing with this problem we shall start from the assumption that the “wing” of the Rayleigh line arises as a result of the scattering of light at fluctuations of anisotropy, i.e., scattering at random deviations from the isotropic distribution of the axes of the anisotropic molecules. The time factor in the resorption of the anisotropy fluctuations determines the spectral composition of the anisotropic scattering. The mathematical relation between the spectral composition of the scattered light and the time characteristics of the attenuation of the fluctuation is established by introducing a time-correlation function. Let us introduce the tensor Sik characterizing the deviation of the distribution of molecular axes in the medium from the isotropic state; we define this tensor so that its mean value over the volume is zero (medium isotropic on average). The tensor Sik should be a function of the angles determining the orientation of the axes of the molecules relative to the stationary (laboratory) system of coordinates x, y, z (indices i, k, etc.).
