โœฆ Synopsis

Stilbene photoisomerizabon 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 timescales 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.

## Abstract Using our recently proposed quantum chemical model to simulate the effect of external forces acting on a molecule (Wolinski and Baker, Mol Phys 2009, 107, 2403), which we subsequently termed enforced geometry optimization (EGO), we investigate structural isomerism in C~14~H~12~, startin
