Abstract
The C-13 CP NMR envelope of as-synthesized crown ether containing inte rgrown faujasite polytype zeolites can be used to determine their FAU and EMT content. The method is calibrated with multiphase Rietveld ref inement of X-ray patterns that are not broadened too much compared to those of the phase pure samples.
