The data were taken from
(1) E. R. Alonso, L. Kolesniková, B. Tercero, C. Cabezas, J. L. Alonso, J. Cernicharo, and J.-C. Guillemin, 2016, Astrophys. J. 832, Art. No. 42.
The reported uncertainties are very conservative; they were reduced by a factor of 2.5, close to the implicitely used uncertaintes. The predictions should be good enough to search for the molecule in space. Transitions with predicted uncertainties of 0.3 MHz or larger should be viewed with great caution.
The dipole moment components were determined by
(2) V. M. Rao and R. F. Curl Jr., 1964, J. Chem. Phys. 40, 3688..
