概要 | Have you ever hoped to observe transition states (TS)? Detailed knowledge of transition states helps find strategies to develop novel reaction schemes for introducing new functionalities to chemicals. Molecular structural changes via TSs can be observed by real-time vibrational spectroscopy using 5-fs pulses. In this paper, I report the direct observation of time-dependent frequency shifts of relevant molecular vibrational modes, which allowed for the clear visualization of ultrafast structural changes in molecules during bond breaking and bond reformation steps. Various mechanisms for photochemical reactions were clarified using 5-fs pulses. Moreover, a non-thermal vibrational excitation method for efficiently driving chemical reactions in the electronic ground state in solution with the use of broadband visible 5-fs pulses has been developed. The respective chemical reaction processes were directly observed, including TSs during not only "photochemical" but also "thermal" reactions. |
