Abstract
Hydrosodalites and hydroxosodalites were analysed by means of 17O, 29Si and 1H MAS NMR in the fields of 17.6 and 11.7 T. The samples covered a range in Si–O–Al bond angle of about 23°. Dependencies between the isotropic 17O chemical shift δ(17O) and the T–O–T bond angle α for the oxygen sites in sodalites, A and LSX zeolites with Si/Al=1 were investigated and found to be linear in some special cases. The adsorption of water and/or cation exchange with larger cations increases the 17O chemical shift.
