Abstract :
Terahertz time domain spectroscopy has been done for reverse micellar solution in the temperature range from ~190 K to room temperature. The temperature dependence of the absorption lineshape demonstrates that dynamics of water in a nanometer-sized droplet change at low temperatures, which will be ascribed to water shedding from reverse micelles.
