Abstract

We report time-resolved absorption studies of the visual pigment rhodopsin with 200 femtosecond resolution. Our data show that he kinetics of rhodopsin is two experimental components. Bathorhodopsin, rhodopsin's early photoproduct, is photochemically formed in 3.0 ± 0.7 ps. A fast transient with an approximately 200 fs which is concluded as the decay of excited state absorption is also observed. Exchange of rhodopsin's exchangeable protons for deuterons does not affect the observed dynamics.
