Proton ENDOR of dimethylnitramine free radicals

  • M. D. Pace
  • T. C. Christidis


Electron nuclear double resonance (ENDOR) spectra of free radicals produced by ultraviolet (UV) photolysis of polycrystalline and single crystal dimethylnitramine (or N-methyl-N-nitromethanamine) [DMN; (CH3)2NNO2 were studied atca. −30°C. Results suggest that multiple radical species are formed during UV photolysis of DMN, perdeutero-DMN-d6, and15N-labeled DMN. Proton ENDOR spectra are consistent with assignment of a cation radical (CH3)2NNO 2 + as the major DMN radical species. Proton hyperfine coupling anisotropy, which is observed from the ENDOR spectra, is attributed to inequivalence of the two DMN methyl groups.
