N2 - The R(0) and R(1) lines of the (3,0) A1Σ+- X1Σ+ band of the major isotopologue of barium sulfide, 138Ba32S, were recorded at high resolution (full width at half maximum ≅35 MHz) and at a field strength of up to 3100 V/cm. The observed Stark shifts were analyzed to produce permanent electric dipole moments, μ→el, of 10.765(8) D and 5.586(22) for the X 1Σ+ (v = 0) and A1Σ+ (v = 3) states, respectively. The relative values of μ→el for barium monoxide, BaO, and BaS are discussed.
