Abstract
The dipole moment and hyperfine constants of OD (and OH) A 2Σ+ have been obtained from ab initio calculations, using self‐consistent field and configuration interaction techniques. Special attention has been given to the effects of basis set quality and vibrational motion. For OD A 2Σ+ in the ground vibrational level, a value of μ = 1.84±0.06 D is obtained. This is consistent with a recent measurement by Weinstock and Zare but not with an earlier determination of Scarl and Dalby.
