摘要：

Stilbene photoisomerization is a useful model system for the investigation of condensed phase reaction dynamics. This manuscript presents data on the photoisomerization of meta-methyl-substituted stilbenes in decane as a function of temperature. These kinetic data indicate that the torsional motion around the bond joining the phenyl ring to the ethylenic carbon occurs on time-scales similar to trans to cis photoisomerization. The results for this model system and previous spectroscopic results suggest that a one-dimensional reaction coordinate may not be appropriate in describing stilbene isomerization. © 1990.
