Time-resolved excited-state triplet-triplet absorption measurements in ..cap alpha..NPO solutions were performed. A concentration quenching effect on the excited absorption and fluorescence spectra, due to excimer formation, was seen. A numerical analysis of the results yielded the rate constants for intersystem crossing, triplet quenching by O/sub 2/, triplet self-quenching, and excimer formation.
