Estimation of the lowest triplet π,π* energy level of 1,4-tetracenequinone by use of triplet energy transfer in solution

Abstract
The triplet energy level of 1,4-tetracenequinone is estimated for the first time to be 42.7 ± 0.3 kcal mol−1 (14930 ± 110 cm−1) by transient absorption measurements of triplet energy transfer in CCl4 at 295 K.
