LASER TECHNIQUE FOR DETERMINATION OF ULTRASONIC VELOCITY

摘要

The physico chemical behaviour of liquids may throw light on molecular interactions. Ultrasonic velocity measurements had been the subject of the recent past. Molecular structure had been determined by Nuclear magnetic resonance, UV, infrared and Microwave techniques. The ultrasonic velocity had been determined by laser ultrasonic interferometric method, a new technique for determination of ultrasonic velocity. Though there are various techniques like 1) Sing around techniques, 2) Variable path interferometer techniques, 3) Pulse echo technique, the laser interferometric method mentioned in this paper seems to be a precise method for determining ultrasonic velocity in aqueous solution of bio - molecules.
