Abstract

The connection between the Rayleigh line wing in inelastic light scattering spectra in liquids and the boson peak observed at light scattering in glasses in the frequency range of 20-100 cm^-1 has been found for the first time. The Rayleigh line wing is represented as a sum of boson and central peaks. The obtained results are evidence of the existence of structural correlations in high-viscosity liquid which decrease exponentially with the distance on the scale of 10 Å.
