Abstract
With increasing magnetic fields and spinning rates, it becomes possible to obtain partly resolved proton spectra in solid state materials using a simple excitation sequence. We present high resolution spectra obtained at high field (14 T) and high spinning rates (30 kHz) for two types of hybrid organic/inorganic compounds: silica matrices doped with pH indicators and mesostructured hybrid silicates templated by surfactant molecules. These first results show that proton solid state NMR at high field and spinning rate should become a tool of choice to characterize interactions between guest molecules and host matrix in sol-gel hybrid materials.
