Sulfur Bonds and the Quadrupole Moments of O, S, and Se Isotopes

Quadrupole couplings of ${\mathrm{S}}^{33}$ in HDS, S${\mathrm{O}}_2$ and C${\mathrm{H}}_3$SH have been measured. These and previously measured quadrupole couplings of ${\mathrm{S}}^{33}$ in OCS, HNCS, CS, and ${\mathrm{S}}_8$ are examined to determine the nature of sulfur bonds and the best value for the ${\mathrm{S}}^{33}$ quadrupole moment. $s-p$ hybridization is found to be common, but not universal, in sulfur bonds. The ${\mathrm{S}}^{33}$ quadrupole moment is -0.064±0.01×${10}^{-24\mathrm{}}$ ${\mathrm{cm}}^2$. If O and Se bonds are assumed to be similar to those of S, the quadrupole moments of ${\mathrm{O}}^{17}$ and ${\mathrm{Se}}^{79}$ are -0.004×${10}^{-24\mathrm{}}$ ${\mathrm{cm}}^2$ and 0.9×${10}^{-24\mathrm{}}$ ${\mathrm{cm}}^2$, respectively.
