Vibration–rotation interaction constants and cubic potential constants were calculated in the small-amplitude approximation. The standard deviations of the rotational constants previously obtained by the microwave measurement were critically examined and found to depend strongly on the centrifugal distortion constants of the infrared data. Although the Coriolis interactions were all neglected, the α and γ constants thus obtained, together with the cubic potential constants, indicate no abnormal feature, in comparison with those of the ordinary triatomic molecules already studied.
