After the spectrum of the depolarized scattering of light in liquids had been observed in [26, 27], a large number of investigations were devoted to the further study of this phenomenon in various substances. The nature of the phenomenon has nevertheless remained uncertain up to the present time. This is partly confirmed by the fact that even recently there have been some papers [28, 29] reporting the “discovery” of maxima in the wing of the Rayleigh line (ordinary thermal scattering) in low-viscosity liquids. Actually, these maxima have no relation to the wing of the Rayleigh line but are a result of the incorrect analysis of experimental data. Apparently the authors of these papers based their treatment on the views of the first investigators (see, for example, [27]), who considered that the Rayleigh-line wing was a Raman spectrum arising as a result of the retarded rotation of anisotropic molecules. Here the liquid was considered as a compressed gas and the wing of the Rayleigh line as the remains of a Raman rotational spectrum.
