It is shown that the excited-state processes in retinal can be consistently explained if an ICT state is included in the relaxation scheme in polar solvents. The results show that a general relaxation scheme employed to explain excited-state dynamics of carbonyl carotenoids can be applied also to retinal. Also, the very short conjugation of retinal supports the notion of asymmetry as a key structural feature controlling the magnitude of the polarity-induced effects.
