Acoustical study in binary liquid mixture containing dimethyl acetamide using ultrasonic and viscosity probes

Ultrasonic velocity (U), density (ρ) and coefficient of viscosity (η) of binary mixture of dimethyl acetamide (DAMC) and acetone at different frequencies (2MHZ, 4MHz 6MHZ, 8MHZ) have been measured at temperature 308K. Adiabatic compressibility (Ks), intermolecular free length (Lf), free volume (Vf), internal pressure (πi) and their respective excess values have been computed for entire range of mole fraction and are interpreted to explain molecular interaction occurring in the liquid mixture. Relaxation time (τ), excess enthalpy (HE) and absorption coefficient (α/f2) have been calculated and discussed.
