Reference sensitizer = MPDME; rel. to phi_Delta(ref. sens.) = 0.80^b. Proportion of T₁ quenched by O₂ = 1.

^a Oxygen concentration not given; assumed to be air saturated.
^b Value of phi_Delta(S') used in this work to calculate phi_Delta(S) from authors'reported phi_Delta(S)/phi_Delta(S').
^T Value corrected for 100% quenching of T₁.
