| Research Abstract |
In this study, we have investigated initial photo-reaction processes of photo-active proteins which shows remarkable response to light irradiation by transient absorption measurement using ultrashort pulse laser with 7.5 femtosecond(10^-15 second) width at time. As a result, we succeeded in the observation of the vibration modes of the chromophoric molecule in the photo-excited state of protein(PYP) which functioned as the eyes of the photosynthetic bacteria for the first time and elucidated that the structure of the protein causes ultrafast isomerization by evoking specific vibration modes of the chromophore.
