Chem. Phys. Lett. 149(2): 161-6 (1988)

Sensitizer: Anthracene, 2-[2-(2-naphthyl)ethenyl]-, (Z)-
Solvent: C₆H₆
Oxygen concentration: 1.3 x 10^-4

Quantum yield of formation = 0.12*; 0.10^T
Fraction of T₁ yielding singlet oxygen = __; 0.45

Experimental method: pulsed laser photolysis
Data type: luminescence intensity at end-of-pulse or under steady-state conditions

Reference sensitizer = BP; rel. to phi_Delta(ref. sens.) = 0.29; meas. phi_T(S) = 0.22; lambda_exc = 355 nm. PSO2 < 0.02 and Proportion of T₁ quenched by O₂ > 0.99.

^T Value corrected for 100% quenching of T₁.
* Values recalculated using phi_Delta(S') or f_Delta^T(S') from Table 4 or from the quoted reference.
