摘要：

The porous structure of a number of silica gels is characterized by Xe-129 NMR of adsorbed xenon. On the basis of experimental data for the samples with well defined structure, an empirical correlation between the Xe-129 NMR chemical shift and the parameters of the porous structure is proposed. The energetic parameters of xenon adsorption have been obtained from the temperature dependence of the chemical shifts. The possibilities and limitations of Xe-129 NMR spectroscopy of adsorbed xenon for studying the porous structure of silica gel are discussed.
