ABSTRACT

To study molecular interactions of compounds in solutions, some acoustical and apparent molar parameters such as acoustical impedance (Z), adiabatic compressibility (κs), intermolecular free length (Lf), molar compressibility (W), Rao’s molar sound function (Rm), Van der Waals constant (b), relaxation strength (r), internal pressure (π), solvation number (Sn), apparent molar compressibility (k), apparent molar volume (v) etc., have been evaluated using experimental data of density (ρ), ultrasonic velocity (U) and viscosity (η) by different equations. The experimental data of density (ρ), viscosity (η) and ultrasound velocity (U) of pure solvents and solutions of synthesized compounds for DMSO at different temperatures.

Keywords: molecular interactions, density, viscosity, ultrasound velocity.
