M. Feuerstein et Rf. Lobo, INFLUENCE OF OXYGEN AND NITROGEN ON LI-7 MAS NMR-SPECTRA OF ZEOLITE LIX-1.0, Chemical communications, (16), 1998, pp. 1647-1648
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 we
re compared with the spectrum of a sample studied in vacuum; it has be
en shown that the line assigned to Li cations at position SIII (delta(
iso) = -0.7) is influenced by the different gases, whereas lines belon
ging to Li cations in front of six-rings do not change (SI' line delta
(iso) = 0.4, SII line delta(iso) = -0.3).
