Outline of Final Research Achievements |
Several studies have clarified that the transition among quasi-stable species with their characteristic structures is essential for protein functioning. The purposes of this study are 1) clarification of an essential role of hydrogen-bond network in the transitions; 2) optical control of the transitions with mid-infrared laser pulses. A femtosecond time-resolved spectroscopy system with high sensitivity was developed based on reaction-trigger UV pulse, tunable mid-infrared pump pulse, and broadband probe pulse. Although a signal change induced by the mid-infrared pulse was clearly observed, it is suggested that the change does not come from the contribution of excited state or intermediate states.
