✦ Synopsis
Radical trapping by nitric oxide in the presence of oxygen has been studied by EsR spectroscopy. The oxygen was found to react much faster with alkyl radicals than nitric oxide, it suppresses formation of dialkyl nitroxides and initiatescreation of acyl nitroxides through reactions between peroxy radicals and nitric oxide.

Formation of macromolecular nitroxides (i.e., spin labeled polymer chains) has been detected by Electron Spin Resonance spectroscopy in the reaction of nitric oxide gas with several unsaturated polymers /synthetic polyisoprene, polybutadiene, poly(isoprene-co-isobutylene), poly(butadiene-co-styrene)
Subsequent trapping of photochemically generated alkyl and alkoxy radicals by nitric oxide yields alkoxyalkylnitroxide radicals. New types of nitrogen centered radicals have been detected and tentatively explained by reactions of nitrogen oxides N20, NO, N02, N203, N204 with alkyl and peroxide radic
