        The microwave data have been reported by T. Thissen, 
H. Spiecker, and P. Andresen, 1999, J. Mol. Spect. {\bf 200}, 
277 and J. A Coxon, K. V. L. N. Sastry, J. A. Austin, and 
D. H. Levy, 1979, Can.\ J. Phys., {\bf 57}, 619. Infrared data
for v = 1 are from T. Amano, 1984, J. Mol. Spect. {\bf 103},
436.  For v = 2, term values up to N = 7 from J. A. Coxon,
1980, Can.\ J. Phys.\ {\bf 58}, 993 were used as synthetic data
with an uncertainty of 150 MHz. For both vibrational states,
H was fixed to the values given in Coxon, 1980.    

        The calculation involved fitting the spectra along with v=0 
data (see species 17001) to effective parameters for the 
$^2\Pi$ states using a Hund's case (b) basis, but the quanta 
have been converted to Hund's case (a).

        The dipole moments are from K. I. Peterson, G. T. Fraser, 
and W. A. Klemperer, 1984, Can.\ J. Phys.\ {\bf 62}, 1502.
