The monomer‐dimer equilibria of 2,6‐ and 3,5‐dimethylnitrosobenzenes in CDCI 3 solution were investigated by 1 H and/or 13 C NMR spectroscopy. The mixed systems nitrosobenzene + 2,6‐dimethylnitrosobenzene and 2,6‐dimethylnitrosobenzene + 3,5‐dimethylnitrosobenzene were also studied, and mixed azodioxy dimers were identified. In all systems exchange occurs exclusively between dimer and monomer species, rates and activation energies being calculated from time‐dependent 1 H 1D spectra and/or 1 H 2D‐EXSY spectra measured at different temperatures.
