Conclusions 1. In the quenching of the triplet state of duroquinone by strong aromatic electron donors, which goes forward with diffusional rate constants, electron transfer is effected. Weak aromatic electron donors in nonsolvating solvents quench the duroquinone triplet through the formation of weak donor-acceptor complexes, and in alcohols through an electron transfer mechanism. 2. In the quenching of a triplet state of duroquinone by secondary aromatic amines and phenols, a hydrogen atom is transferred; this is accomplished in nonpolar exciplexes, or it may be a result of proton transfer in a radical pair that has been formed after electron transfer.
