✦ Synopsis

Triplet-triplet absorption spectra of coumarin and 7-hydrox~coumarin in rigid alcoholic solutions at 1 IFE; were reco&ed. Measurement of ground state depletion allowed the determination of the molar extinction coefficients of the triplet bands, for both compounds. CNDO/S calculations of the triplet-triplet transitions were performed and an assignment of the observed bands was attempted.

Triplet-triplet absorption of biphenylene was sensitized by naphthalene. A band is observed at 29 500 cm-l and is assigned to a predicted 3B& + 3B& transition. Triplet biphenylene has a lifetime of 100 psec in solution. Nonradiative processes are thought to affect mainly the first singlet state of b
