The observed transitions were taken from
(1) D. T. Halfen, D. J. Clouthier, and L. M. Ziurys, 2008, Astrophys. J. 677, L101.
With respect to the Apr. 2008 entry, Fourier transform microwave data were used in the fit. The data were reported in
(2) D. T. Halfen, M. Sun, D. J. Clouthier, and L. M. Ziurys, 2009, J. Chem. Phys. 130, Art.-No. 014305.
Predictions with uncertainties larger than 0.5 MHz should be viewed with caution. Moreover, all predictions for the higher-lying Π3/2 spin component should be viewed with great caution.
The ab initio dipole moment was taken from
(3) J. El-Yazal, J. M. L. Martin, and J.-P. François, 1997, J. Phys. Chem. A 101, 8319.
