Ultrasonic study of molecular interactions in some bio-liquids

Abstract

The velocity of ultrasonic wave of frequency 10 MHz has been measured by the ultrasonic Time Intervalometer using pulse echo overlap method, in the temperature range 100 to 550C, for the bio-liquids. Cinnamaldehyde, acrolein, acrylonitrile, methylmethacrylate, methanol, p-dioxane and cyclohexane. The relative strength of intermolecular interaction has been found to depend upon the presence of electron-donar and electron-accepter group. The ultrasonic parameters found useful in determining the relative strength of homo-molecular interaction in pure liquids
