The combined fit of several isotopic species and the first excited state of the main isotopolog was described by
(1) H. S. P. Müller, K. Kobayashi, K. Takahashi, K. Tomaru, and F. Matsushima, 2015, J. Mol. Spectrosc. 310, 92.
Hund's case b quantum numbers were employed as usual. Data were used with reported uncertainties for the most part, some were adjusted. Multiple rotational data were only retained in case of similar uncertainties, usually only the ones with smaller uncertainties were used. Some data with residuals much larger than the uncertainties were omitted. Millimeter and lower submillimeter data of the main isotopolog were taken from

Submillimeter and terahertz data were taken from
(3) T. D. Varberg, F. Stroh, and K. M. Evenson, 1999, J. Mol. Spectrosc. 196, 5.
Λ-doubling transitions in v = 0 were mainly taken from
(4) W. L. Meerts and A. Dymanus, 1972, J. Mol. Spectrosc. 44, 320.
Additional v = 0 Λ-doubling transitions were taken from
(5) R. M. Neumann, 1970, Astrophys. J. 161, 779;
and from
(6) W. L. Meerts, 1976, Chem. Phys. 14, 421.
Further v = 0 as well as v = 1 Λ-doubling transitions were reported by
(7) R. M. Dale, J. W. C. Johns, A. R. W. McKellar, and M. Riggin, 1977, J. Mol. Spectrosc. 67, 440;
and by
(8) R. S. Lowe, A. R. W. McKellar, P. Veillette, and W. L. Meerts, 1981, J. Mol. Spectrosc. 88, 372.
Millimeter and lower submillimeter data of 15NO were taken from
(9) A. H. Saleck, K. M. T. Yamada, and G. Winnewisser, 1991, Mol. Phys. 72, 1135.
Submillimeter and terahertz data were taken from (3), Λ-doubling transitions from (4).
Millimeter and lower submillimeter data of N18O were taken from (9), terahertz data from (1).
Millimeter data of N17O and 15N18O were published by
(10) A. H. Saleck, M. Liedtke, A. Dolgner, and G. Winnewisser, 1994, Z. Naturforsch. 49a, 1111.
NO heterodyne IR transition frequencies were reported by
(11) A. Hinz, J. S. Wells, and A. G. Maki, 1986, J. Mol. Spectrosc. 119, 120;
and by
(12) S. Saupe, B. Meyer, M. H. Wappelhorst, W. Urban, and A. G. Maki, 1996, J. Mol. Spectrosc. 179, 13.
The partition function includes v = 0 and 1.
The dipole moment was reported by
(13) Y. Liu, Y. Guo, J. Lin, G. Huang, C. Duan, and F. Li, 2001, Mol. Phys. 99, 1457.
The magnetic dipole moment was estimated from γ in (1).
Concerning Hund's case a quantum numbers, levels with J + 0.5 = N correlate with 2Π1/2 and levels with J – 0.5 = N correlate with 2Π3/2 for J ≤ 5.5; the correlation is reversed for J ≥ 6.5.
