The fit combines pure rotational as well as rovibrational data of three isotopic species. The OH rotational data were taken from
(1) F. Matsushima, T. Yonezu, T. Okabe, K. Tomaru, and Y. Moriwaki, 2006, J. Mol. Spectrosc., 235, 261
; and
(2) D. J. Liu, W. C. Ho, and T. Oka, 1987, J. Chem. Phys., 87, 2442.
The OD rotational data were published by
(3) G. Cazzoli and C. Puzzarini, 2005, J. Chem. Phys., 123, Art.-No. 041101
; and
(4) G. Cazzoli and C. Puzzarini, 2006, Astrophys. J., 648, L79.
With respect to the first entry from Dec. 2006, a new J = 1 – 0 transition frequency as well as rovibrational data of OH were taken from
(5) P. Jusko, O. Asvany, A.-C. Wallerstein, S. Brünken, and S. Schlemmer, 2014, Phys. Rev. Lett., 112, Art. No. 253005
Rovibrational transitions for OH and 18OH were taken from
(6) N. H. Rosenbaum, J. C. Owrutski, L. M. Tack, and R. J. Saykally, 1986, J. Chem. Phys., 84, 5308
those of OD from
(7) B. D. Rehfuss, M. W. Crofton, and T. Oka, 1986, J. Chem. Phys., 85, 1785
Predictions with J > 10 should be viewed with some caution; lower-J predictions may be fairly reliable if and only if ion drift effects had negligible effects on the infrared data.
The ab initio dipole moment was taken from
(8) H.-J. Werner, P. J. Rosmus, and E.-A. Reinsch, 1983, J. Chem. Phys., 79, 905.
