The experimental measurements were summarized by (1) G. Klapper, F. Lewen, S. P. Belov, and G. Winnewisser, 2000, Z. Naturforsch. 55a, 441;
the sextic centrifugal distortion constant H was taken from
(2) G. Guelachvili, G. De Villeneuve, R. Farrenq, W. Urban, and J. Verges, 1983, J. Mol. Spectrosc. 98, 64.
The dipole moment and dipole centrifugal corrections are taken from
(3) D. Goorvitch 1994, Astrophys. J. Suppl. 95, 535.
The splitting due to the 13C nucleus has been taken into account in the calculation of the partition function.
