## Abstract The primary step in the bleaching sequence of visual pigments has been shown to occur in picoseconds, while the isomerization of model visual pigment chromophores, protonated 11โ__cis__ retinylidene Schiff bases, takes place on a time scale several orders of magnitude slower. Thus, the

We analyze the kinetics of a pigment system with thermal and photochemical transitions among its states. The general mathematical description is obtained and is then specialized to systems with two stable states (states with negligible thermal outlets) in which the total amount of pigment is conserv
