Redmond, R.W.; Scaiano, J.C.
J. Phys. Chem. 93(14): 5347-9 (1989)

Sensitizer: Acetophenone, 2'-methyl-, biradical
Solvent: CH₃CN
Oxygen concentration: air^a

Quantum yield of formation = 0.23^T
Fraction of T₁ yielding singlet oxygen = 0.38

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

Reference sensitizer = Ac; rel. to phi_Delta(ref. sens.) = 0.83; lambda_exc = 337 nm. f_Delta^T based on quantum yield of biradical formation = 0.60 in soln. contg. 0.012 mol L^-1 2-methylacetophenone.

^a Oxygen concentration not given; assumed to be air saturated.
^T Value corrected for 100% quenching of T₁.
