摘要：

The D NMR spectra of HD and ortho D2 are sensitive to the crystal fields from the MgO surface sites. At fractional coverages 0.6 < x < 0.9, beyond the limit of island growth, rapid motion among inequivalent sites occurs, even at 4.2 K. For 1 < x < 2, broad and narrow lines arise from the first and second layers, respectively. Isotopic bilayer mixtures show nearly complete separation, with the more massive specie in the first layer.
