Ammonium Dinitramide: An EPR/ENDOR Study
Abstract
Ammonium dinitramide (NH4N(NO22,ADN) is an oxidizer with potential applications in aerospace technology. Based on its chemical formula, ADN can decompose to form reactive nitrogen metabolites (RNMs). The decomposition characteristics of ADN powder following exposure to non-ionizing and ionizing radiation were studied. Electron paramagnetic resonance (EPR) spectroscopy was used to determine if radiation induces chemical change in ADN by formation of free radicals. Most free radicals are highly reactive and they will attempt to gain an electron from other compounds in order to pair with their odd electrons. Irradiated ADN powder generated two superimposed EPR spectra. These spectra have tentatively been identified as NO2 and NH3 radicals. To verify the EPR results, electron nuclear double resonance (ENDOR) was utilized. The initial results of these experiments suggest a proton interaction proximal to the NH3 radical center. In biological systems both reactive oxygen metabolites (ROMs) and RNMs play an important role in normal physiology and pathophysiology. The effects of decomposition products of ADN in biological systems should be studied by addressing ADNs effect on the balance between ROMs and RNMs.
