Abstract

Magnetic field dependent recombination measurements together with magnetic field dependent triplet lifetimes [Chidsey et al. (1985), Proc. Natl. Acad. Sci USA 82, 6850] allowed the determination of the free energy change ΔG(P+H−−3P*) = 0.15–0.16 eV between 185K–290K. This value being (almost) temperature independent indicates ΔG(P+H−−3P*) ≃ ΔH(P+H−−3P*) and is consistent with ΔG(1P*−P+H−) and ΔH(1P*−3P*) from previous delayed fluorescence and phosporescence data implying ΔG ≃ ΔH for all combinations of these states.
