Solvent dielectric effects on isomerization dynamics: Investigation of the photoisomerization of 4,4'-dimethoxystilbene and t-stilbene in n-alkyl nitriles

Article abstract of DOI:10.1063/1.455971

New data for the photoisomerization dynamics of t-stilbene and 4,4'-dimethoxystilbene in polar sovents are reported.These data demonstrate that in n-alkyl nitriles, nonassociated polar solvents, it is possible to extract a solvated barrier for the isomerization.This result is contrasted with recent studies in n-alkyl alcohols, associated polar solvents, where this separation is not possible and clarifies the origin of the changing barrier height in n-alkyl alcohols.Comparison of reduced isomerization rates with models of chemical reaction dynamics in solution are drawn.Good agreement of the data with a coupled oscillator model is found.
