Barrierless photoisomerization of 11-cis retinal protonated Schiff base in solution

Abstract:

A hallmark of the primary visual event is the barrierless, ultrafast, and efficient 11-cis to all-trans photoisomerization of the retinal protonated Schiff base (RPSB) chromophore. The remarkable reactivity of RPSB in the visual pigment rhodopsin has been attributed to potential energy surface modifications enabled by evolution-optimized chromophore-protein interactions. Here, we use a combined synthetic and ultrafast spectroscopic approach to show that barrierless photoisomerization is an in...
