Study of molecular properties using acoustic non-linearity parameter in the ternary liquid mixtures at different temperatures

Abstract

The parameters of non-linearity (B/A) of ternary liquid mixtures, namely phenol and o-cresol with dimethyl sulfoxide (DMSO) in carbon tetrachloride have been evaluated at 293.15, 303.15 and 313.15 K. The non-linearity parameter has been computed by three different methods, namely Tong and Dong's method, Beyer's method and Beyer's method using Tong–Dong coefficients. The excess values of non-linearity parameter (B/A)^E have also been evaluated and discussed in the light of intermolecular interactions present in the liquid mixtures. Sehgal's relations for evaluating molecular properties for pure liquids are extended to ternary liquid mixtures.
