ResumoThe quantum yield for the isomerization and its concentration dependence were determined for 1-(2-anthryl)-3,3-dimethyl-1-butene, and the T1 → Tn absorption spectra were measured for the cis and trans isomers of several 2-anthrylethylenes. The spectra were assigned to their planar triplets, the intermediate of the “one-way” isomerization proceeding through an adiabatic quantum chain process on the triplet manifold.
