In this chapter, we will present the results of an investigation into the effects of a polymeric cationic compound upon the direction of the crystallization and the formation of a novel layer silicate type based on earlier work [11, 18-20]. The novel layer silicates were characterized by chemical and physical methods, especially by x-ray difrraction (XRD), high-resolution electron microscopy (HI M), and magic-angle-spinning nuclear magnetic resonance (MAS NMR).

We present a solid-state nuclear magnetic resonance (NMR) experiment that allows the observation of a high-resolution two-dimensional heteronuclear correlation (2D HETCOR) spectrum between aluminum and phosphorous in aluminophosphate molecular sieve VPI-5. The experiment uses multiple quantum magic angle spinning (MQMAS) spectroscopy to remove the second order quadrupolar broadening in Al nuclei. The magnetization is then transferred to spin-1/2 nuclei of P via cross polarization (CP) to produce for the first time isotropic resolution in both dimensions.
