Conclusions 1. Quenching of triplet states of ketones by nitroxyl radicals occurs by charge transfer and by energy transfer from the triplet molecule to the radical. The relative contributions of these mechanisms depends on the triplet energy of the ketone and the electron donor ability of the radical. 2. Quenching of the triplet state of anthanthrone by nitroxyl radicals occurs by charge transfer from the radical to the triplet molecule. Products of electron or hydrogen atom transfer in this case are not formed as a rule. Their formation is possible under conditions where the radical contains a fragment which is a stronger quencher than the radical center.
