摘要
Nitrogen and oxygen were adsorbed in dehydrated samples of zeolite LiX-1.0 [(SiAlO4)(96)Li-96]; the Li-7 MAS NMR spectra of these samples were compared with the spectrum of a sample studied in vacuum; it has been shown that the line assigned to Li cations at position SIII (delta(iso) = -0.7) is influenced by the different gases, whereas lines belonging to Li cations in front of six-rings do not change (SI' line delta(iso) = 0.4, SII line delta(iso) = -0.3).
