An electron spin resonance study of the reaction of aliphatic amines and OH-with 4nitroveratrole (NV) in its lowest electronic triplet state is presented. It is concluded that both nucleophiles transfer an electron to triplet-state NV in the first chemical step of the reaction. This is then followed
