Abstract
Some of the peculiar phenomena occurring in the aqueous solutions have been studied using an ultrafast Baser. It is observed that the dynami cs of the intramolecular charge transfer process is markedly retarded when the probe solute is transferred from bulk water to the interior o f various hydrophobic aggregates. Solvation dynamics of water molecule s in various organized and biological environments is found to be more than thousand times slower than that in ordinary water, Lastly, sever al processes occurring at tile water surface have been studied using t he novel surface second harmonic generation technique.
