There are many techniques available to study physical properties to interpret the molecular interaction in liquids, liquid mixtures and solutions. The study of ultrasonic waves through solution is found to be quite interesting. The study of ultrasonic waves through solution is used for knowing the nature and strength of intermolecular forces and their interaction in liquids, liquid mixtures and solutions. Thermo-acoustical and its allied properties are very helpful in predicting the physico-chemical behavior and molecular interactions occurring in liquids, liquid mixtures and solutions. Hence this motivates the researchers to take up the research project in the field. Here we are interacting Aspirin drug particles with liquid solution of ethanol and polymer Polyethylene glycol to study the interactions and to study the absorption rate of drug particles. Physicochemical properties of drugs are of great interest to understand ‘drug action’ at molecular level. By varying acoustical parameters and sonication time respective acoustical parameters are obtained.
