| Outline of Final Research Achievements |
In this work, a new time-resolved infrared spectroscopy that enables us to achieve picosecond time resolution and nanosecond energy resolution, utilizing pico- and nano- second lasers. This method was applied to solvated clusters in the gas phase to investigate solvation dynamics from individual molecular point of view.
It was clarified that mechanism of solvation dynamics is classified into two-cases; repulsive and attractive cases depending on the solute-solvent interaction potential. In both cases, intracluster vibrational energy redistribution (IVR) plays a key role. It is important, however, that the direction of the energy flow is opposite. It was also found that the solvation dynamics rate can change more than three-orders of magnitude for the two cases.
