A Program of Study on the Aggregation of Molecules and Their Effect on Sound Propagation.

Abstract

This final report outlines the accomplishments of the study of the aggregation of molecules and their effect on sound propagation. A theoretical approach has been developed to analyze non-linear sound propagation applicable to aggregating medium. Experimental techniques such as dielectric relaxation over a frequency range of 100 Hz to 3 gega Hz, and ultrasonic vibration potential over a range of 0.2 to 2 MHz were developed. Measurements have been made on a micellar forming anionic paraffin chain salt sodium dodecyl sulfate, SDS and a cationic paraffin chain salt dodecyl triammonium bromide, DTAB. A dielectric relaxation was found for SDS and DTAB attributed to a shell of interfacial water around the hydrocarbon core of the micelle.
