The observed transitions were summarized in
(1) T. Amano and A. Maeda, 2000, J. Mol. Spectrosc. 203, 140
.
The dipole moment is assumed to be the same as in the ground vibrational state, see e029504.cat.
The first excited bending state, v2 = 1, see e029505.cat, has been taken into account in the calculation of the partition function. Its energy for J = 1 was determined ab initio in
(2) M. Mladenovic and S. Schmatz, 1998, J. Mol. Spectrosc. 109, 4456
.
The individual contributions of v2 = 0 and 1 are given in parentheses. The second quantum number (v) is basically redundant.
