The experimental data have been taken from
(1) R. J. Halter, R. L. Fimmen, R. J. McMahon, S. A. Peebles, R. L. Kuczkowski, and J. F. Stanton, 2001, J. Am. Chem. Soc., 123, 12353.
Predictions may be sufficiently reliable if the uncertainties do not exceed 100 kHz.
14N hyperfine structure may be resolved for transitions with small quantum numbers. Therefore, a separate hyperfine calculation is provided up to J = 10. NOTE: The partition function does take into account hyperfine splitting !
The experimental dipole moment components are from (1).
