Outline of Final Research Achievements |
Ultrafast electron dynamics and non-adiabatic chemical reactions in pure liquids and solutions were traced in real time through changes in the kinetic energy and angular distributions of photoelectrons emitted through the liquid surface. For this purpose, we pioneered ultrafast photoemission spectroscopy, especially using extreme ultraviolet ultrashort pulses generated by high-order harmonic generation. We have succeeded in measuring the ground-state electron binding energy and the solvation time of solvated electrons in water, methanol, and ethanol, and tracking the internal conversion of solvated electrons from their excited state to the ground state in real time. We have also extended our research to the studies of photochemical reactions of various organic molecules and ions near the gas-liquid interface. The ultrafast extreme ultraviolet photoelectron spectroscopy was also applied to the fundamental gas-phase reactions such as the electrocyclic ring-opening reactions.
