Retinal chromophore of rhodopsin photoisomerizes within picoseconds

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.
