Abstract
The frequency shift Δv of the fine structure components of Rayleigh light scattering in 4-methylpyridine water solutions is studied in the ranges of 1 — 0.1 mole fraction concentrations and temperature 10 — 80 °C. The laws of Δv variation at different light scattering angles are discussed from the viewpoint of solution structural reorganisation under the varying temperature and concentration of nonelectrolyte in water. Existence of a continuous hydrogen-bond net in the solutions is experimentally proved in a certain range of temperatures and concentrations.
