Abstract

The electron paramagnetic resonance (EPR) spectrum of nitrogen afterglow condensed on the walls of a microwave cavity at 4.2[degrees]K indicates the presence of considerable quantities of ground state nitrogen atoms. The hyperfine coupling constant for the [...] state is estimated at [...]. Frozen dissociation products of ammonia produced the same nitrogen resonance line and, in addition, the resonance spectrum for atomic hydrogen.
