The red-shifted bright ππ* state (S₂) behaves like the lower and more productive dark nπ* (S₁) state because less potential energy along the planar bending mode is available to reach higher energy unproductive nπ*/S₀ crossing regions, which are responsible for the lower quantum yield of the parent compound. The stabilization of the bright ππ* state and the consequent increase in isomerization efficiency may be regulated via the strength of push-pull substituents. Finally, the torsional mechanism is recognized here as the unique productive route because structures with bending values attributable to the inversion mechanism were never detected, out of the 280 ππ* time-dependent density functional theory (RASPT2-validated) dynamics simulations.21:T4c9,By combining UV transient absorption spectroscopy with sub-30-fs temporal resolution and CASPT2/MM calculations, we present a complete description of the primary photoinduced processes in solvated tryptophan. Our results shed new light on the role of the solvent in the relaxation dynamics of tryptophan. We unveil two consecutive coherent population transfer events involving the lowest two singlet excited states: a sub-50-fs nonadiabatic L_a → L_b transfer through a conical intersection and a subsequent 220 fs reverse L_b → L_a transfer due to solvent-assisted adiabatic stabilization of the L_a state.
