Nuclear magnetic resonance has been employed to identify the phases of the system NbNx in several samples of niobium nitride. The ϵ phase has been identified by a characteristic second‐order quadrupolar broadened central transition with two sets of satellite lines also being observed. The quadrupole coupling constant has been determined for the ϵ phase (e2qQ/h=10.6±0.1 MHz) and for the δ phase (e2qQ/h=4.3±0.4 MHz). The relative amounts of the phases present in a sample were also determined in two samples.
