Transitions were reported by
(1) V. D. Gordon, M. C. McCarthy, A. J. Apponi, and P. Thaddeus, 2002, Astrophys. J. Suppl. Ser. 138, 297.
The assigned uncertainties are close to those assumed implicitely.
Predictions with Ka > 2 were omitted because of lack of experimental data. Predictions should be good enough to identify the molecule in the cold and dense ISM. They should be viewed with caution above 47 GHz.
The dipole moment was estimated.
