Direct Observation of the Conical Intersection in cis-trans Photoisomerization of Rhodopsin

Not Accessible

Your library or personal account may give you access

Abstract

High-time-resolution broadband pump-probe spectroscopy of rhodopsin reveals loss of reactant and appearance of photoproduct features within ≈100fs, which are signatures of a wavepacket moving through a conical intersection. Experiments are supported by molecular dynamics simulations.
