Nuclear-Magnetic-Resonance Study of the Hydrogen Nucleus in OH−in the Potassium Chloride Lattice

Experimental data are presented on the nuclear-magnetic-resonance signal from the hydrogen magnetic-dipole moment in the O${\mathrm{H}}^{-}$ ion substituted for ${\mathrm{Cl}}^{-}$ in a KCl lattice. The recovery rate of the signal after saturation is measured for O${\mathrm{H}}^{-}$ concentrations down to 1.2×${10}^{19}$ O${\mathrm{H}}^{-}$/${\mathrm{cm}}^3$. This rate is used to deduce a displacement distance = 0.4×${10}^{-8\mathrm{}}$ cm for the hydrogen nucleus from the halogen vacancy site when the O${\mathrm{H}}^{-}$ ion has -directed localized states in a rigid lattice and a correlation time = 4×${10}^{-8\mathrm{}}$ sec. The effects of librating states of the O${\mathrm{H}}^{-}$ and lattice relaxation are estimated. A discussion of the dependence of the displacement distance on the correlation time is included.
