摘要：

The adsorption isotherms and Xe-129 NMR chemical shifts of xenon in the voids of zeolite Y with 0%. 53%, 75%, and 95% exchange of copper (II) for sodium ions were determined. With increasing copper content the shifts go upfield. The local chemical shifts of xenon at a crystallographic SII site with and without the charge compensating sodium ion are concluded to be 60 and 32 ppm, respectively.
