✦ Synopsis

behave as a boundary case distinguishing between one-way and two-way isomerizations. Introduction of an alkyl group (R=t-Bu) and an aryl group (R=Ph) on the P_ethylenic carbon leads to the one-way and two-way isomerization, respectively. Their triplet energy surfaces are proposed on the basis of measurements of the quantum yields, photostationary isomer ratios, and T-T absorption spectra.
