The dipole moment was measured by J. S. Muenter and W. Klemperer, 1970,
J.~Chem.~Phys.~{\bf 52}, 6033.  The molecular parameters are derived from a fit
to far-infrared and infrared data supplied by J. A. Coxon (personal
communication) and from the submillimeter measurement of P. Helminger {\it et
al.}, 1970, Phys.~Rev.~Lett.~{\bf 25}, 1397.  See also  J. A. Coxon and  P. G.
