Abstract

A supersonic molecular beam of iron monohydride, FeH, has been generated using a laser ablation/chemical reaction scheme and probed at near-natural linewidth resolution by optical Stark spectroscopy utilizing laser-induced fluorescence detection. The observed Stark splitting in Q (3.5) and R (3.5) lines of the F Δ 72 4 X Δ 72 4 (1,0) transition were analyzed to determine values for the magnitudes of the permanent electric dipole moments, ∫μ∫, which were found to be 2.63(3) and 1.29 (3) D for the X Δ4 (v=0) and F Δ4 (v=1) states, respectively. A comparison with ab initio theoretical predictions is made. The doubling in the low- J levels of the F Δ 72 4 (v=1) state is also modeled.
