Retinal chromophore of rhodopsin photoisomerizes within picoseconds.

G Hayward, W Carlsen, A Siegman, L Stryer.   

Abstract

A new picosecond resonance Raman technique shows that resonance Raman lines characteristic of a distorted all-trans retinal appear within 30 picoseconds after photolysis of rhodopsin or isorhodopsin. This finding suggests that isomerization is nearly complete within picoseconds of the absorption of a photon.
