"Nature of acid or basic sites, their amount and distribution of their strength in the zeolitic lattice belong to the most important problem of surface chemistry. The aim of our study was to estimate the location of chemisorbed species in the lattice and to elucidate the role and participation of lattice oxygen types in chemisorption of methylium ions. We have decided to carry out our experimental study on well developed crystals of NaX and NaLSX zeolites with high content of sodium cations and with low content of defects and decationation. Distribution of chemisorbed methyl groups and sodium cations in the structure of NaX and NaY zeolites was studied by neutron diffraction and NMR technique." . .
