Summary, etc. Ultrasonic, volumetric and viscometric investigations have been carried out on DMSO + formamide and DMSO + N, N-dimethylformamide mixtures at three temperatures 293, 303 and 313 K over the entire mole fraction range. From these data, deviation in isentropic compressibility (<em>ΔK</em><sub>s</sub>), excess Gibb’s free energy of activation for viscous flow (<em>ΔG<sup>*</sup></em><sup>E</sup>), excess internal pressure (<em>π</em><img src="http://www.niscair.res.in/jinfo/ei.gif" border="0" alt="" />) and excess molar enthalpy (<em>H</em><img src="http://www.niscair.res.in/jinfo/em1.gif" border="0" alt="" />) have been calculated. A Redlich-Kister polynomial equation of third degree has been used to correlate the derived properties of binary liquid mixtures by using the least square method. The observed positive and negative values of excess parameters have been used to study the nature and strength of intermolecular interactions present in these mixtures. Further, theoretical values of ultrasonic velocity have been evaluated using theories and empirical relations.
