Abstract
Summary form only given. Visual excitation is initiated by the absorption of a photon by the 11-cis retinal chromophore bound within the pigment called rhodopsin. The photochemical cis-trans isomerization in rhodopsin is complete in only 200 fs. The extreme speed of this process suggests that the photochemistry involves nonstationary states or vibrational coherence.
