Abstract

The [17.6]2← X3δ1(1,0) band of tungsten monocarbide, WC, was recorded using laser induced fluorescence both field-free and in the presence of a static electric field. The Stark induced shifts of the R(1) and Q(2) lines were analyzed to produce values for the permanent electric dipole moments, μ, of 3.90±0.04 D and 2.57±0.04 D for the X3δ1(v 0) and [17.6]2(v = 1) states, respectively. An upper limit to the ω-doubling parameter, õδ, of 2 MHz is established. The 183W(I = 1/2) Fermi contact parameter, bF, for the X3δ1(v = 0) is estimated to be 1363 MHz. The results are compared with theoretical predictions and a molecular orbital correlation description.
