The experimental transition frequencies were reported by
(1) C. A. Gottlieb, M. C. McCarthy, M. J. Travers, J.-U. Grabow,
and P. Thaddeus, 1998, J. Chem. Phys. 109, 5433.
The fit has been carried out using parameters and quantum numbers of Hund's case (b).
The highest frequency rotational transition was omitted because
of large residuals. The remainder of the lines was deeemed to be
uncertain to 1 kHz.
No 1H hyperfine splitting was resolved in the laboratory;
it may be resolvable for the lowest transitions.
Calculations of the upper 2Π1/2 component
were omitted because no experimental data are available.
Calculations of the lower 2Π3/2 component
may be reliable up to about 50 GHz.
Please not that the partition function is not converged at high
temperatures, but it should be fine up to about 150 K.
The dipole moment has been estimated.
