| Research Abstract |
Using pump-dump-probe spectroscopy, we studied the dynamics of reacting molecules near the conical intersection region that plays crucial roles in ultrafast reactions. The data clearly showed that the dump efficiency rises up more slowly for dumping with longer wavelengths, revealing the wavepacket migration toward the conical intersection region along the reaction coordinate. We also realized uv-resonance femtosecond stimulated Raman spectroscopy with tunable uv pulses, and using this, we revealed that the chromophore of photoactive yellow protein undergoes a rapid in-plane deformation within 1 ps after photoexcitation.
