The viscosity dependence of chemical reactions in solution reveals various aspects of solute-solvent interactions. This paper is concerned with the dynamic solvent effects on isomerizations in solution. The isomerization accompanying large amplitude motion due to bulky atomic groups serves as a prototype for this purpose. The isomerization of 2-vinylanthracene in S<SUB>1</SUB>-excited state has been studied over a wide solvent viscosity range from supercritical fluids to compressed liquids. The "Kramers turnover" behavior has been observed . The turnover region was simulated by a single curve of an additive formula. The dynamic solvent effect on the isomerization accompanied with intramolecular charge-transfer is described by the shift of reaction path, which is called "pressure tuning" effect.
