The experimental measurements were described in J.C. Pearson and B.J. Drouin, 2005, J. Mol. Spectrosc. 234, 149. The dipole of the OH specicies was assumed for the OD species. The catalog contains the calculated frequencies from a quadratic interaction analysis.  The catalog analysis differs from the paper in that the constants that resulted in significant differences between torsional substates were fixed together.  This allowed $D_{bc}$ to be determined, but due to lack of real information on the a-type resonance the value is probably not trustworthy.

The data set is quite limited with a few low $J$ $^a$R branches and a few c-type at low frequency.  The poorly determined a-type interaction will strongly affect the asymmetry splitting at low $K_a$ and higher $J$.  As a result the $K_a$ transitions for 0,1,2 will be problematic above $J$=20.  $K_a$ values between 3 and 7 will be some what better possibly to between $J$=25 and 35.  Above $K_a$=10 there is no data and the calculation is not believable.
