The transitions frequencies were reported by
(1) O. Martinez, Jr., V. Lattanzi, S. Thorwirth, and M. C. McCarthy, 2013, J. Chem. Phys. 138, Art. No. 094316.
14N hyperfine splitting was resolved in some transitions.
Predicted transition frequencies with Ka = 0 may be reliable up to 120 GHz, those with Ka = 1 maybe up to 80 GHz. Data involving still higher Ka should be viewed with even greater caution.
14N hyperfine splitting can be resolved at low quantum numbers. Therefore, a separate calculation with 14N hyperfine splitting is provided up to J' = 3 and Ka = 1 together with partition function values.
The a-dipole moment component is from a calculation in (1); b-transitions can not be predicted reliably at present.
