The ultrasonic velocity (U), density () and coefficient of viscosity () of binary mixture of dimethyl acetamide (DAMC) and diethyl ether at temperature 308K have been measured at different frequencies (2MH, 4MHz 6MHZ and 8MH). Adiabatic compressibility (K), intermolecular free length (L), free volume (V), internal pressure (πi) and their respective excess values have been computed for entire range of concentration and are interpreted to explain molecular interaction occurring in the liquid mixture. Relaxation time (ζ), excess enthalpy (HE) and absorption coefficient (a/ƒ2) have been calculated and discussed.
