ResumoAbstract The trans-isomer ratio of 1-p-biphenylyl-3,3-dimethyl-1-butene (BDMB) at the photostationary state in triplet sensitized isomerization increases with increasing concentration of oxygen and azulene. It is proposed to classify triplet energy surfaces of some aromatic olefins containing BDMB based on the variation of their photostationary isomer ratios with oxygen and/or azulene as triplet quenchers in their photoisomerization.
