The rotational transition frequencies were reported by
(1) S. Takano, S. Yamamoto, and S. Saito, 1989, Chem. Phys. Lett. 159, 563.
Additional parameters were taken from
(2) N- Anderson and S. P. Davis, 2001, Phys. Scr. 64, 446.
Predictions should be reliable up to about 1.0 THz.
Vibrational contributions have been considered in the calculation of the partition function. Values for the ground state are given in parentheses.
The dipole moment has been taken from an ab initio calculation by
(3) K. A. Peterson, 2010, unpublished.
