With respect to the Sep. 2005 entry, a new set of rotational transitions for CF+ and 13CF+ was used in acombined fit. These transitions were measured by
(1) G. Cazzoli, L. Cludi, C. Puzzarini and J. Gauss, 2010, Astron. Astrophys., 509, A1.
The uncertainties were confirmed to be judged conservatively; 20 kHz were used here.
As previously, infrared transitions were taken from
(2) K. Kawaguchi and E. Hirota, 1985, J. Chem. Phys., 83, 1437.
In addition, data were used from
(3) M. Gruebele, M. Polak, and R. J. Saykally, 1986, Chem. Phys. Lett., 125, 165.
Some higher order parameters were kept fixed to values from (3) which were derived from a fit to potential coefficients. Predictions should be viewed with caution above 1.5 THz. The excited state predictions should be viewed with some caution throughout.
The partition function takes into account vibrational states. Individual contributions > 0 are given in parentheses.
The ab initio dipole moments come from
(4) K. A. Peterson, R. C. Woods, P. Rosmus, and H. J. Werner, 1990, J. Chem. Phys., 93, 1889.
