Transition frequencies with resolved 14N hyperfine structure were reported by
(1) T. Brupbacher, R. K. Bohn, W. Jäger, M. C. L. Gerry, T. Pasinszki, and N. P. C. Westwood, 1997, J. Mol. Spectrosc. 181, 316.
Transition frequencies without resolved HFS were reported by
(2) H. Lichau, S. C. Ross, M. Lock, S. Albert, B. P. Winnewisser, M. Winnewisser, and F. C. De Lucia, 2001, J. Phys. Chem. A 105, 10080.
The calculations should be sufficiently accurate for all kinds of observations.
A separate hyperfine calculation is provided for J" ≤ 10.
NOTE: The partition function does take into account the spin multiplicities gI = 3 of the 14N nuclei !
The dipole moment was taken from an ab initio calculation in (1).
