Abstract

Number average molecular weights for lecithin micelles in toluene were determined by osmometry at 25 and 40 °C to be 54 000 and 41 900 respectively. The weight average molecular weights were found to be 78 000 and 68 000 for the same two temperatures by Brillouin spectroscopy. This new technique shows promise in determining micelle size.
