Abstract

The optical Stark spectra of the R(4) and Q(4) lines of the [18.8] 3p4-X3p4(0,0) band systems of cobalt monofluoride, CoF, and the A′3p4-X 3p4(0,0) band systems of cobalt monohydride, CoH, have been recorded using laser induced fluorescence technique. The shifts and splittings caused by the static electric field have been analyzed to give the permanent electric dipole moments, μe, of 4.51(5) and 2.82(5) D for the [18.8]3p4 and X3p4 states of CoF, and 0.01(8) and 1.88(8) D for the A′3p4 and X3p4 states of CoH. The experimental dipole moments are compared with theoretical predictions. A molecular orbital correlation description is used to explain the relative ground state μe values for CoH and CoF.
