The dipole was measured by Takagi and Saito. The $H_K$ constant was
fixed to the IR/microwave/electronic value of J. W. C. Johns, A. R. W.
McKeller and E. Weinberger, 1983, Can. J. Phys. {\bf 61}, 1106.
 
The molecule was first observed in interstellar emission by B. L. Ulich,
J. M. Hollis and L. E. Snyder, 1977, Astrophys. J. {\bf 217}, L105.
