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.
Rovibrational transitions for OH and 18OH were taken from
(5) J. C. Owrutski, N. H. Rosenbaum, L. M. Tack, and R. J. Saykally, 1985, J. Chem. Phys., 83, 5338
those of OD from
(6) B. D. Rehfuss, M. W. Crofton, and T. Oka, 1986, J. Chem. Phys., 85, 1785
Predictions should be viewed with caution, in particular those with J > 10.
The dipole moment was assumed to agree with that of the main isotopic species, see e017502.cat.
