The electron spin resonance of nitrogen dioxide trapped in frozen nitromethane, chloroform, carbon tetrachloride, and water were studied over a wide range of temperatures. In all solvents a triplet spectrum observed near -100° split into many lines when the temperature was raised. Simultaneously, the hyperfine splitting constant due to interaction of the unpaired electron with the N 14 magnetic moment decreased from 55 to about 12 G. The multiline spectra were interpreted in terms of an interaction between NO 2 and N 2O 4.
