摘要：

The decay processes of the excited singlet state and potential energy surfaces of 1-(3,3-dimethyl-1-butenyl)pyrene (BP) were investigated. A long-lived fluorescence from the cis isomer and involvement of a quantum chain process for one-way isomerization suggest that the isomerization on direct excitation proceeds in the triplet manifold after intersystem crossing at the cis conformation.
