Millimeter and submillimeter data were reported by
(1) H. S. P. Müller, A. Brahmi M., J.-C. Guillemin,
F. Lewen, and S. Schlemmer,
2021, Astron. Astrophys. 647, Art. No. A179.
Earlier, limited microwave data were taken from
(2) R. C. Benson, W. H. Flygare, M. Oda, and R. Breslow,
1973, J. Am. Chem. Soc. 95, 2772.
The data have been truncated at J = 50 and 500 GHz.
Transition frequencies involving Ka > 12
should be viewed with caution.
The dipole moment of the main isotopolog was determined in (2).
A tiny b-dipole moment component, caused by the asymmetry
of the molecule, was ignored.
