Time-resolved Spectroscopic Studies of Photoexcited Retinal Isomers in Solution and the Mechanism of Photoisomerization
The photophysiscs and photochemistry fololwing the photoexcitation of retinal isomers in hydrocarbon solutions have been studied by nanosecond time-resolved spontaneous Raman, nanosecond time-resolved infrared absorption, picosecond time-frequency two-dimensional CARS, picosecond time-resolved fluorescence, and femtosecond visible absorption spectroscopies. The mechanism of the cis-trans photoisomerization of retinal is discussed on the basis of the accumulated time-resolved spectroscopic data.
