Triplet-State Kinetics of 2,5 Diphenyloxazole (PPO)

Volume 42, Number 1 (Jan. 1988) Page 27-31

Dharamsi, A.N.; Jong, Shawpin

Time-resolved excited-state triplet-triplet absorption spectra were measured for solutions of 2,5 diphenyloxazole (PPO) in various solvents, with the use of a pump and probe technique. The rate constants for intersystem crossing, triplet deactivation by oxygen, and triplet-triplet self-quenching are obtained. The latter two rate constants are substantially larger than the corresponding rate constants for 2-(1 naphthyl)-5-phenyloxazole-αNPO.
