The experimental measurements were analyzed using the methods described
in W. H. Kirchhoff, 1972, J. Mol. Spect. {\bf 41}, 333.  The
measurements were taken from: B. Fabricant, D. Krieger, and J. S.
Muenter, 1977, J. Chem. Phys. {\bf 67}, 1576. J. W. C. Johns, J. M. R.
Stone, and G. Winnewisser, 1972, J. Mol. Spect. {\bf 42}, 523. H. R.
Johnson and M. W. P. Strandberg, 1952, J. Chem. Phys. {\bf 20}, 687.
	
The dipole moment was reported by Johnson (above) and B. Fabricant {\it
et al.} (above).
