The experimental data were taken from
(1) L. Kolesniková, I. Peña, E. R. Alonso, B. Tercero, J. Cernicharo, S. Mata, and J. L. Alonso, 2018, Astron. Astrophys. 619, Art. No. A67.
A small fraction of lines were taken from
(2) H. Hirono, J. Shibano, A. Mitani, T. Sakaizumi, M. Onda, O. Ohashi, and I. Yamaguchi, 1987, J. Mol. Struct. 162, 359.
The predictions are probably sufficient for all needs of astronomers. Predictions with uncertainties larger than 0.3 MHz should be viewed with caution.
The dipole moment was determined in (2).
