Picosecond time-resolved fluorescence spectra of all-trans retinal in hexane have been measured with 8 ps time-resolution with use of a highly sensitive streak camera. The observed fluorescence consists of a fast (r < 1 ps, ,h.ma x m 470 nm) and a slow (r = 33-34 ps, Ama x --540 nm) component. The l

โฆ Synopsis
Picosecond time-resolved absorption spectra of all-tram-and 9-cis-retinal in n-hexane solution have been measured by using an Nd3+:YAG laser photolysis system. A drastic change of the T,+T, absorption spectrum of the 9-cis isomer has been observed in the picosecond to nanosecond time region, which should reflect the configurational relaxation in the triplet state.

Time-resolved absorption spectroscopy was applied to the triplet species produced by anthracene-sensitized flash photolysis of the all-trans, 7-c&, 9-c& 13-c& and 1 S-cis isomers of g-carotene. Upon triplet excitation, the a&trans and 154s isomers produced an identical triplet species showing the sa
Femtosecond-picosecond time-resolved absorption spectral measurements on 9,9'-bianthryl in polar alkanenitrile solvents revealed that the rise curve of the charge-transfer (CT) state contained components with rise times considerably longer than the solvent 7L, which indicated the importance of the t
