The observed transitions were summarized in
(1) T. Amano and A. Maeda, 2000, J. Mol. Spectrosc. 203, 140
.
The dipole moment is from an ab initio calculation by
(2) Y. Yamaguchi, C. A. Richards, and H. F. Schaefer III, 1994, J. Chem. Phys. 101, 8945
.
The first excited bending state, v2 = 1, see e029505.cat, has been taken into account in the calculation of the partition function. The individual contributions of v2 = 0 and 1 are given in parentheses. The second and third quantum numbers (v and l) are basically redundant.
