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