摘要：

Properties of chrysene in the higher triplet excited state were studied by the two-color two-laser flash photolysis method. Triplet energy transfers from chrysene in the higher triplet excited state to quenchers such as biphenyl and naphthalene, and from the quenchers in the triplet excited state back to chrysene in the ground state were observed to proceed at the diffusion-controlled rate. From dependence of the quenching efficiency on the quencher concentration, the lifetime of chrysene in the higher triplet excited state was estimated to be 60 ps with considering the time-dependent quenching.
