The experimental transition frequencies were taken from
(1) R. Gendriesch, F. Lewen, G. Klapper, K. M. Menten, G. Winnewisser, J. A. Coxon, and H. S. P. Müller, 2009, Astron. Astrophys., 497, 927.
Predictions beyond 2.5 THz should be viewed with some caution for v = 2 and 3.
The partition function takes into account all vibrational states up to v = 3; individual contributions are given in parentheses. At temperatures considerably higher than 1000 K contributions from states with v > 3 are not negligible.
The dipole moment and its centrifugal distortion corrections were taken from
