Is the Photoinduced Isomerization in Retinal Protonated Schiff Bases a Single- or Double-Torsional Process?
Result description
Nonadiabatic photodynamical simulations are presented for the all-trans and 5-cis isomers of the hepta-3,5,7- trieniminium cation (PSB4) to characterize the types of torsional modes occurring in the cis-trans isomerization processes in retinal protonatedSchiff base (RPSB), the rhodopsin and bacteriorhodopsin chropomhore. The most important mechanism driving restricted PSB4 isomerization in the excited state is characterized by two concerted twist motions (bipedal and closely related to it nonrigid bipedal), with only one torsion tends to relax into the ground state.
