Date of EntrySep. 2026
ContributorH. S. P. Müller

Transitions frequencies were taken from
(1) L. Margulès and S. Bailleux, 2026, J. Mol. Spectrosc. 420, Art. No. 112098.
The calculated transition frequencies should be reliable for most observational purposes. Caution is advised above 750 GHz.
The dipole moment is assumed to agree with that of the main isotopolog, see e046527.cat.
