| 英文摘要 | The ultrafast photoisomerization process of retinal in Bacteriorhodpsin's (BR) photocycle was investigated via femtosecond time-resolved absorption spectroscopy. Singular value decomposition (SVD) combined with model-based global fitting was employed to analyze the time-resolved spectra, and the related difference spectra (SADS) and the population dynamics of I-460, J(625) and K-590 intermediates were derived on the basis of our proposed reaction scheme. The detailed photoisomerization pathways were discussed. Moreover, the SADS of Franck-Condon state (H intermediate), radiative transition of which accounts for the stimulated emission around 700 nm, was also detected, and its time constant was 0.04 ps. Our results prove the involvement of the H-intermediate in ultrafast photoisomerization process of retinal in BR. |
