The optical Stark spectrum of the A1Σ-X1Σ+(0, 0) band of BaO was recorded and analyzed to determine the permanent electric dipole moments, μ, for the A1Σ(ν = 0) and X1Σ+(ν = 0) states to be 3.125(16) D and 7.869(17) D, respectively. The molecular beam electric resonance data for the X1Σ+(ν = 0) states [L. Wharton, M. Kaufman, W. Klemperer, J. Chem. Phys. 37 (1962) 621] was re-analyzed to produce μ of 7.9530(4) D. The systematic difference between the MBER and optical Stark values is discussed.
