The experimental data were taken from

The calculation should be sufficiently accurate for astronomical
observations. Transitions with calculated uncertainties
exceeding 0.1 MHz should be viewed with some caution.
This applies in particular to the weaker b-type lines
with Ka = 2 and higher.
Fine structure as well as hyperfine structure caused
by the 14N and each of the inequivalent H
may be resolvable in astronomical observations.
A separate calculation with
5 quantum numbers is also provided; besides
the common rotational quanta, these are an aggregate spin number
and F.
The dipole moment components are from a quantum chemical
calculation in (1).
