Dioxygen: What Makes This Triplet Diradical Kinetically Persistent?

This article examines experimental heats of formation and enthalpies obtained from G4 calculations to find that the resonance stabilization of the two unpaired electrons in triplet O₂, relative to the unpaired electrons in two hydroxyl radicals, amounts to 100 kcal/mol.
