Abstract

A number of low- N lines of the X +6 A +6 (0,0) band of chromium monodeuteride, CrD, have been recorded at near the natural linewidth limit by high resolution laser excitation spectroscopy of a supersonic molecular beam sample. The shifts and splitting of these lines caused by a static electric field have been analyzed to give the permanent electric dipole moments of the X +6 (=0) and A +6 (=0) states as 3.510(33) and 1.153 (3) D, respectively. The dipole moment of the A +6 (=0) state can be measured with higher precision because of some interesting near degeneracies in its level structure. The trends in the observed dipole moments for the first-row transition metal monohydrides are rationalized and compared with theoretical predictions.
