The data were taken from 
T. Ogata, Y. Ohshima, and Y. Endo, 
1995, J. Am. Chem. Soc. {\bf 117} 3593.

The dipole moment is from an $ab \ initio$ calculation: 
N. Moazzen-Ahmadi and F. Zerbetto, 
1995, J. Chem. Phys. {\bf 103}, 6343.

The partition function has been calculated up to $J$ = 360 
because of the low rotational constant.
