Kumar, C.V.; Davis, H.F.; Das, P.K.
Chem. Phys. Lett. 109(2): 184-9 (1984)

Sensitizer: 9-Acridinethione, 10-methyl- (NMTA)
Solvent: c-C6H12
Oxygen concentration: O2

Fraction of T1 yielding singlet oxygen = 1

Experimental method: pulsed laser photolysis
Data type: time resolved substrate disappearance; sensitizer triplet absorbance at end-of-pulse

Singlet oxygen acceptor = DPBF; Triplet actinometer = S; meas. phiT(S) = 0.79; lambdaexc = 485 nm; used kd = 5.0 x 104 s-1, kA = 3.4 x 108 L mol-1 s-1, epsilonT(S) = 8800 L mol-1 cm-1 at 520 nm. Measured Proportion of T1 quenched by O2.
