N2 - Infrared gas phase spectra of ONCN, ONC15N, ON13CN, O15NCN, 18ONCN, O15NC15N, O15N13CN, 18ONC15N and 18ON13CN have been recorded. A general harmonic force field (with six constraints) has been derived based on the assigned fundamental vibration frequencies and checked by calculation of experimental values for centrifugal distortion constants, a Coriolis coupling constant and the inertial defect. The harmonic force field of a fully optimized structure of ONCN as found by the Pulay force method is reported and compared to the experimental force field. No essential disagreements were found.
