Various acoustical properties such as isentropic compressibility, specific impedance, molar sound velocity, molar compressibility, van der Weals constant, intermolecular free length, excess molar volume (V-E), excess viscosity, excess adiabatic compressibility, Gibb's free energy of activation for viscous flow etc. have been calculated in three binary systems: anisole + methanol, anisole + chloroform and anisole + dimethyl foramide from sound velocity (2 MHz), density and viscosity measurements at 30 degreesC. The results are interpreted in terms of molecular interactions occurring in the solutions.
