Several sets of rotational, rovibrational, and electronic data were fit simultaneously. These include the v = 0 ground state rotational transitions along with extensive higher frequency v = 0 and 1 terahertz and FIR data from
(1) M. A. Martin-Drumel, S. Eliet, O. Pirali, M. Guinet, F. Hindle, G. Mouret, and A. Cuisset, 2012, Chem. Phys. Lett. 550, 8.
Also included are rotational data from
(2) E. Klisch, T. Klaus, S. P. Belov, A. Dolgner, R. Schieder, G. Winnewisser, and E. Herbst, 1996, Astrophys. J. 473, 1118;
as well as radiofrequency data from
(3) W. L. Meerts and A. Dymanus, 1974, Astrophys. J. 187, L45.
Terahertz data from
(4) B. J. Drouin, J. C. Pearson, S. Yu, and H. Gupta, 2013, IEEE Trans. Terahertz Sci. Technol. 3, 314;
were omitted from the fit because a considerable fraction of the data is not compatible with the remaining data within uncertainties. Additional v = 0 FIR rotational data from
(5) I. Morino and K. Kawaguchi, 1995, J. Mol. Spectrosc. 170, 172;
were superseded by the more extensive and more accurate data from (1).
Also included in the fit were rovibrational data from
(6) P. F. Bernath, T. Amano, and M. Wong, 1983, J. Mol. Spectrosc. 98, 20;
(7) R. J. Winkel, Jr., and S. P. Davis, 1984, Can. J. Mol. Phys. 62, 1420;
and from
(8) R. S. Ram, P. F. Bernath, R. Engleman, Jr., and J. W. Brault, 1995, J. Mol. Spectrosc. 172, 34.
P. F. Bernath is thanked for an output file of his fit in (8) which was used as orientation of uncertainties of (6-8).
In addition, v = 0 – 0 rovibronic data were employed in the fit which were taken from
(9) D. A. Ramsay, 1952, J. Chem. Phys. 20, 1920.
Transitions with uncertainties larger than 100 kHz have not been merged.
Predictions of transitions within each spin-substate should be reliable throughout mainly because of the extensive data from (1) and (7). Transitions between the spin-substates should be viewed with some caution.
Hund's case (b) quantum numbers were employed, as usual. Levels with J + 0.5 = N correlate with 2Π1/2 and levels with J – 0.5 = N correlate with 2Π3/2.
The experimental dipole moment was determined in (3). Rotational corrections to the dipole moment may matter at higher rotational quantum numbers.
