Electron paramagnetic resonance analysis of dimethyl amidogen in polycrystalline tetramethyl tetrazene.

Abstract

The photolytic decomposition of tetramethyl-2-tetrazene yields a short-lived paramagnetic species which is stabilized at liquid nitrogen temperatures. For the analysis of the electron paramagnetic resonance spectrum the species has been identified as the free radical dimethyl amidogen. The hyperfine coupling tensors were assigned on the basis of a polycrystalline line shape analysis. The radical exhibits axial symmetry with the parallel components of the tensors greater than the perpendicular components. The limits of error associated with the components of the tensors were estimated from the general comparison of the calculated and observed spectra.
