摘要：

Structure and dynamics of chemically modified silica gels have been investigated by high-resolution solid-state NMR spectroscopy. Si-29 cross-polarization magic angle spinning (CP-MAS) NMR spectroscopy yields information on variety and quantity of surface species of both pure silica gel and modified silica gel. C-13 CP-MAS NMR spectroscopy reveals dynamic properties of the attached alkyl chains. The data from Si-29 and C-13 solid-state NMR spectroscopy can be correlated with the separation characteristics in high-performance liquid chromatography.
