The experimental lines are from
(1) L. Bizzocchi and C. Degli Esposti; 2004, Astrophys. J. 614, 518.
The vibrational energy is from an ab initio calculation by
(2) P. Botschwina, M. Horn, K. Markey, and R. Oswald, 1997, Mol. Phys. 92, 381.
NOTE: The partition function values are those of v = 0 ! They do NOT take into account vibrational contributions ! Information on vibrational contributions to the partition function are available.
The dipole moment has been assumed to be identical to that of the ground vibrational state, see e099501.cat.
