The experimental data was taken from
(1) M. Bogey, C. Demuynck, and J. L. Destombes, 1989, Chem. Phys. Lett. 155, 265; and from
(2) Y. Oshima and Y. Endo, 1993, Chem. Phys. Lett. 213, 95.
For transitions with N = 5 – 4 or higher, the hyperfine splitting is smaller than ca. 1 MHz for the strong hfs components. Therefore, predictions without hyperfine structure are also available.
The dipole moment is from an ab initio calculation by
(3) P. W. Fowler and A. J. Sedlej, 1991, Mol. Phys. 73, 43.
