Abstract

The optical Stark effect in the (0, 0) A²Π-X²Σ⁺ band systems of a yttrium monosulfide, YS, supersonic molecular beam sample have been analyzed to produce the magnitude of the permanent electric dipole moments, |μ|, for the A²Π_3/2, and A²Π_1/2 states of 5.9(2), and 6.8(1) D, respectively. Small splittings in the field free A²Π_3/2-X²Σ⁺ and A²Π_1/2-X²Σ⁺ spectra were analyzed to produce the magnetic hyperfine spectroscopic parameters a = -36(6), c = 111(7), and d = -107(6) MHz for the A²Π state. Transition frequencies of the low rotational lines in the (0, 0) A²Π_r-X²Σ⁺ band system were measured and analyzed to produce the first complete set of the structure parameters for the A²Π_r state. A comparison with YO and other isovalent molecules is made.
