A simultaneous analysis of ν 4, ν 5, ν 6, and the ground state of DN 3 has been performed based on data from microwave, far-infrared, infrared, and Raman gas-phase spectra. The analysis takes into account resonance between the ground state and ν 5 due to centrifugal distortion, a- and b-Coriolis resonances between ν 5 and ν 6, and a-Coriolis resonance between ν 6 and ν 4. A set of spectroscopic constants for all four levels and a number of interaction parameters have been obtained. The following values for the ground state rotational constants have been obtained: A 0 = 11.499517(3) cm −1, B 0 = 0.3786230(7) cm −1, C 0 = 0.3657530(7) cm −1.
