The adsorption isotherms and the {sup 129}Xe NMR chemical shifts of xenon sorbed in the supercages of partially and fully silver exchanged zeolites NaX and NaY after vacuum dehydration as well as after subsequent oxygen treatment were determined. The unusual displacements of the chemical shifts upfield from those found for the sodium forms are attributed to specific interactions of xenon with silver cations in the supercages. It is concluded that after vacuum dehydration at 400 and 500 C no silver cluster are formed in the supercages with the possible exception of the fully silver exchanged zeolite AgX.
