The 14N hyperfine splitting has been resolved in the ISM/CSM at low values of J. Therefore, separate predictions with 14N hyperfine splitting are available for J" ≤ 10. NOTE: The partition function does NOT take into account the hyperfine splitting and no vibrational contributions ! The partition function has to be muliplied by g(14N) = 3 when 14N hyperfine splitting is considered ! Information on vibrational contributions to the partition function is available.
The dipole moment was assumed to agree with that of the main isotopomer, see e051501.cat.
