The IR transitions were taken from: Haese, Liu and Altman, 1984, J. Chem.\ Phys.\ {\bf 81}, 3766. Additional information on excited vibrational states and the electronic states is reviewed in W. Stwalley {\it et al.}, 1991, J. Phys.\ Chem.\ Ref.\ Data {\bf 20},153. The dipole moment for the parent species of Langhoff {\it et al.}, 1986, J. Chem.\ Phys.\ {\bf 85}, 5158 was assumed. The values of Y$_{12}$, Y$_{03}$, and Y$_{13}$ were constrained by isotope relations to values from the main isotope.
