Microwave transition frequencies were taken from
(1) H Dreizler, H. D. Rudolph, and B. Hartke, 2004, J. Mol. Struct., 698, 1.
Millimeter wave transition frequencies were taken from
(2) Z. Kisiel and A. Krasnicki, 2010, J. Mol. Spectrosc., 262, 82.
Uncertainties were conservative and were adjusted. Predictions should be reliable throughout.
Spin-statistics have been considered in the calculation of the intensities. They are 5 : 3 for transitions with even and odd Ka, respectively.
The dipole moment was determined in
(3) A. P. Cox, I. C. Ewart, W. M. Stigliani, 1975, J. Chem. Soc. Faraday Trans. II, 71, 504.
