Abstract

The fluorescence relaxation kinetics from all-trans retinal in polar and non-polar solvents have been investigated as a function of temperature. An activation energy of ≈1 keal/mole has been measured. Our results, in conjunction with previous picosecond absorption measurements made by Hochstrasser et al., strongly suggest that initially excited molecules to Franck-Condon states relax to three singlet excited states.
