The purely K-dependent terms A, DK etc. were assumed to agree with those of the main isotopolog, see e041505.cat.
The predictions are probably reliable throughout.
The vibrational identifier 0 indicates levels with k ≤ 0, and 1 indicates levels with k > 0.
14N hyperfine splitting may be resolvable at low values of J and possibly at the highest K. Therefore, predictions with hyperfine splitting have been provided up to J" = 11 (230 GHz); along with appropriate partition function values. Note: Vibrational contributions have not been considered in the calculation of the partition function yet. Rough estimates may be obtained by scaling the respective ground state value with the ratio from the main isotopolog.
The dipole moment was assumed to agree with that of the main isotopolog, see e041505.cat.
