Application of recently developed solid-state NMR techniques to microporous materials such as zeolites and AlPO4 has been introduced. The connectivity of X-Y spin pairs can be examined by dipolar dephasing difference (or TRAP-DOR), cross polarization (CP), REDOR and TEDOR experiments. Those techniques are applied to study the connectivity of Al-O-P and Al-O-Si in the framework structure. They are also applied to study the surface property in terms of the interaction between the surface and adsorbed molecules containing N and P. High resolution solid-state NMR spectra of half-integer quadrupole nuclei such as 27Al and 23Na can be obtained by two-dimensional multiple-quantum spectra under MAS, which has been applied to study Al sites in AlPO4.
