| Abstract: | A millimeter wave molecular beam maser has been used to resolve the nuclear hyperfine structure of the 110 → 101 transition of D2S at 91.4 Gc/sec. This data, combined with that previously obtained for H2S and HDS, allows a determination of the molecular constants of hydrogen sulfide. The quadrupole coupling constants for D2S are (eQqj)110 = 17.83 ± 0.15 kc/sec and (eQqj)101 = −10.82 ± 0.28 kc/sec. The components of χii = eQDqii in its principal axis system are χxx = 149.0 kc/sec, χyy = −59.8 kc/sec, and χzz = −89.2 kc/sec, where the z axis is perpendicular to the plane of the molecule and the x axis is rotated 1°35′ from the DS bond in the direction away from the D-S-D obtuse angle. |
