Research Field

Analysis of Reaction Mechanisms, Laser Chemistry.

Research Subjects

  • 1. Visualization of transition states with 5-fs visible laser pulses.
  • 2.Development of novel reactions induced by coherent molecular vibrational excitation.

Introduction:

Reactions induced by coherent molecular vibrational excitation in the electronic ground state just after photoexcitation are triggered by 5-fs visible laser pulses. The transition states in thermal reactions are observed by using reactions induced by coherent molecular vibration.
