摘要: ABSTRACT Anisotropic chemical shifts were measured for 129 Xe sorbed in ALPO-11 and NMe 4 montmorillonite. The loading dependence was explained terms of dynamic averaging a statistical distribution three distinguishable xenon types. Discrete populations atoms AgA zeolite give information on Ag siting, diffusion processes. Evidence is presented that low temperature NMR properties NaY often are artifacts produced by poor thermal conduction.
