The lines have been reported by
(1) M. A. Brewster, A. J. Apponi, J. Xin, and L. M. Ziurys,
1999, Chem. Phys. Lett. 310, 411.
With respect to the initial entry from Nov. 2000,
additional microwave transitions with resolved
23Na hyperfine splitting have been used in the
calculation. These were reported by
(2) P. M. Sheridan, M. K. L. Binns, M. Sun, J. Min, M. P.
Bucchino, D. T. Halfen, L. M. Ziurys,
2011, J. Mol. Spectrosc. 269, 231.
The stated uncertainties in (1, 2) appear to be too
conservative; smaller values have been employed here.
Predictions may be reliable up to 600 GHz.
A separate prediction with
23Na hyperfine splitting is available for
J" ≤ 5. Note:
The partition function does not include the
spin-multiplicities of 23Na ! Therefore,
partition function values have to be multiplied by 4
when considering 23Na hyperfine splitting !
The dipole moment is from an ab initio calculation
