Abstract
The Landau–Placzek ratio (LPR) is measured in glycerol and triacetin in a wide temperature (viscosity) range. It is attempted to explain a sharp change in the LPR based on the Isakovich and Chaban theory [1] which assumes a two-component structure of viscous liquid. It is shown that the LPR strongly depends on the cluster concentration, and their sizes remain unchanged.
