Electron paramagnetic resonance spectrometry was used to characterize and measure the concentration of nitrogen dioxide dissolved in water, carbon tetrachloride, n-hexane, acetone and benzene at 290 K. Solutions were monitored by ultraviolet spectrometry. We measured the equilibrium constant for N2O4 plus NO2 dissolved in n-hexane and carbon tetrachloride. In order to investigate the formation of organic nitroxide type intermediates, some experiments were designed to examine the role of NO and NO plus NO2 mixtures.
