Description	Powder samples of NaLSX faujasite in dehydrated state and with absorbed methyl iodide were investigated by neutron diffraction and 13C MAS NMR. The distribution of Na+ cations and chemisorbed methylium ions in the frame of NaLSX was estimated by Rietveld refinement. Surface methoxy group were located mostly at O1 and O4 lattice oxygen. The changes in populations of cations sites after chemisorption were detected.

(en) Práškové vzorky faujasitů NaLSX v dehydratovaném stavu a s chemisorbovanými methylovými grupami byly zkoumány difrakcí tepelných neutronů a 13C MAS NMR. Distribuce Na+ kationtů a chemisorbovaných iontů v základním strukturním skeletu NaLSX byly určeny Rietveldovou metodou. Povrchové methoxylové skupiny byly vázány především na mřížkové kyslíky O1 a O2. Byly pozorovány změny v obsazovacích číslech kationtů po chemisorbování methylovými grupami. (cs)
