Popis:	Cross-polarization (CP) combined with magic-angle spinning (MAS) is the most popular technique used for the high-resolution solid 13 C study of occluded templates in zeolitic materials. Depending on the mobility of the incorporated templates the high-power decoupling (DEC) technique is more suitable to detect and to quantify templates in zeolites. By this technique, high-resolution MAS NMR spectra, displaying quantitative reliable 13 C signal intensities of the occluded templates, are obtained in ZSM-5, SAPO-37 and the mazzite structure.
