Analysis of deuterium nuclear magnetic resonance line shapes in anisotropic media

摘要

Methods for the analysis of motional effects on2H NMR solid state line shapes are described. Several simple models of anisotropic motions in solids are presented from which line shapes and relaxation experiments are calculated. Using these methods order parameters of fast limit spectra can be explicitly evaluated. These methods are extended to include analysis of intermediate exchange spectra in terms of specific motional models. The effects of differentialT2rsquo;s arising from exchange broadening on the line shape in powders are described. Methods for the calculation and analysis ofT1anisotropy in partially relaxed spectra of powders for both fast and intermediate exchange regimes are presented.
