Measurement of the pure rotational spectrum of NiCN in its 2Δi ground electronic state has enabled the identification of both spin-orbit components of this molecule, as well as new vibronic levels. It has confirmed the linear cyanide structure of this radical, as indicated by optical studies. In the higher lying spin-orbit sublevel, significant lambda-doubling interactions are observed, as is found in NiH(X2Δi).
