The submillimeter-wave spectrum of hydrogenisocyanide, HNC, in its ground vibrational and first excited bending states (vibrational states are denoted ) has been measured from 453 to 1991 GHz spanning the rotational quantum numbers . The new transition frequencies were fitted together with previously published data, providing a comprehensive set of molecular parameters up to sextic centrifugal distortion constants. The present data set allows for the prediction of accurate rest frequencies well beyond 2 THz.
