Measurement of the vibrational state dependence of the LiH A 1Σ+ dipole moment

Article abstract of DOI:10.1063/1.440425

Zero field molecular level crossing spectroscopy in the J' = 2 rotational state has been employed to measure the electric dipole moment μ_ν of several vibrational levels v' of the LiH A ¹Σ⁺ excited electronic state.The dipole moments are determined to be μ₁ = 1.88+/-0.19 D, μ₂ = 1.49+/-0.18 D, and μ₅ = 0.29+/-0.05 D, where the quoted uncertainties represent 95percent confidence intervals.These experimental values are found to agree rather well with vibrationally averaged dipole moments from the ab initio calculation by Docken and Hinze .The extreme dependence of μ_ν on vibrational level is striking and, on the basis of the ab initio results, can be ascribed to a change in the electronic structure of the LiH A state with internuclear separation.
