| Research Abstract |
In order to clarify the specialties of water above the gas-liquid critical temperature (supercritical water), we have selected the molecules which shows the intra-molecular charge-transfer as target, and studied the electronic states, structure, and electron transfer dynamics which is induced by the photo-excitation, using various kinds of laser spectroscopy and theoretical calculations. We have clarified for the first time the hydrogen-bonding between solute and solvent in protic supercritical fluids, and the details of the electron transfer reaction and the vibrational energy relaxation.
