The electron spin resonance spectra of nitrogen dioxide dissolved in several unsaturated solvents consisted of triplets with an average 14N splitting of about 13 G. Two triplets of equal intensity were recorded in solvents which had aromatic as well as olefinic character, the splitting of the triplet being due to interaction with a single solvent proton. The results were interpreted in terms of formation of an NO2-olefin π complex in an exothermic process. This precedes the well-known reaction which leads to nitration of the olefin.
