摘要：

Xe-129 nuclear magnetic resonance (NMR) of xenon coadsorbed in NaY zeolite with carbon tetrachloride at 144 K has been studied as a function of the xenon loading. The NMR spectra reveal two types of Xe-129 resonances corresponding to xenon in supercages with and without CCl4 molecules. The presence Of CCl4 molecules in the supercage suppresses the gas-liquid transition of the xenon sharing the same cage. On the other hand, the gas-liquid transition of xenon in the supercages without CCl4 molecules can influence the distribution of the carbon tetrachloride in the zeolite.
