Hyperacoustic parameters of solutions at different temperatures

A great contribution to the study of the liquid state can made by elucidating the nature of structural changes in liquid molecules at various state parameters. Optical methods will give us the opportunity to obtain more, complete information about nature of structural changes in molecules. One of these methods based on the study of the spectra of the Mandelstam-Brillouin scattering of light. Investigations of the spectra of Mandelstam-Brillouin scattering of light in solutions and the study of hyperacoustic parameters from them are another method for studying the molecular nature of intermolecular interactions in liquids. We have studied hyperacoustic parameters in a solution of aniline nitrobenzene at various concentrations and temperatures. As can be seen from the results obtained, with an increase in the proportion of aniline in the solution, an increase in the speed and f z frequency of hypersound and a decrease in the calculated value of the adiabatic compressibility - . As can be seen from the data obtained, with an increase in the proportion of aniline in the solution, the hyperacoustic parameters change as a function of the viscosity described by formula (2).
