Transition frequencies without hyperfine structure splitting were taken from
(1) T. Okabayashi and M. Tanimoto, 1996, J. Chem. Phys. 105, 7421.
Transition frequencies with hyperfine structure splitting were taken from
(2) K. Katoh, T. Okabayashi, M. Tanimoto, Y. Sumiyoshi, and Y. Endo, 2004, J. Chem. Phys. 120, 7927.
The partition function takes into account vibrational corrections approxomately and also the HFS splitting. The predictions should be sufficiently accurate for observational purposes. Some caution is advised for frequencies with calculated uncertainties exceeding 0.2 MHz.
19F hyperfine splitting may be resolved for low values of J. Therefore, a separate hyperfine calculation is provided for frequencies below 211 GHz.
The dipole moment was calculated by
(3) J. F. Harrison and J. H. Hutchison, 1999, Mol. Phys. 97, 1009.
