Abstract

We investigate the excitation wavelength and solvent viscosity dependence of the rate of formation and distribution of ground-state isomers in a Landau-Zener (LZ) electronic transition from the excited state. We find that both the rate and the distribution depend strongly on the excitation wavelength. A viscosity-mediated cross-over from a dynamic LZ transition to one governed by an exponential gap law is predicted.
