Vibration–rotation transitions in the ν1, band of the CCN free radical in the [Formula: see text] state have been observed by CO laser magnetic resonance (LMR) spectroscopy. The observations have been combined with existing diode laser data to determine the parameters of an N2 effective Hamiltonian modified to include the Renner–Teller effect in the [Formula: see text] state explicitly. The LMR observations are well modelled by estimated Zeeman parameters that take into account non-adiabatic vibronic interactions. The analysis suggests a small systematic error in the diode laser measurements and leads to a revision of the band origin, ν1, to 1923.252 92 (42) cm−1.
