With respect to the May 2007 entry, several submillimeter transitions up to about 785 GHz were used in the fit. They were published by
(2) T. Amano, 2008, J. Chem. Phys. 129, Art. No. 244305
14N hyperfine splitting was resolved for J" ≤ 1. Therefore, a separate calculation with 14N hyperfine splitting is provided up to J" = 4. The partition function takes into account the spin multiplicity gI = 3 of the 14N nucleus !
Unresolved hyperfine splitting for the J" = 2 and 3 or the different discharge conditions may affect the transition frequencies slightly outside the stated uncertainties. Nevertheless, the predictions should be reliable up to about 2 THz.
The ab initio dipole moment was mentioned in (1).
