experiments we have determined values of the mean free path 1 of xenon adsorbed on various zeolites. We deduce from them the dependence of the chemical shift S on 1. It is now possible to determine the dimensions of any cavity in which xenon can be adsorbed.
The adsorption isotherms and lz9Xe NMR chemical shifts of xenon in the voids of zeolite Y with O%, 53%, 75%, and 95% exchange of copper (II) for sodium ions were determined. With increasing copper content the shifts go uptield. The local chemical shifts of xenon at a crystallographic SII site with a
