Cage molecules, xenon interaction

The effect of the co-adsorption of organic molecules on the Xe NMR spectra of xenon atoms adsorbed on zeolite NaY was studied by De Menorval et al. [327]. They found that the NMR shift depends on the kind of guest molecules, their concentration, and the density of xenon atoms inside the zeolite cages. The differences in the interaction of xenon atoms with aromatic molecules (benzene and trimethylbenzene) in comparison with saturated hydrocarbon chains like n-hexane were explained by an adsorption of the aromatic hydrocarbons parallel to the cage walls while the hydrocarbon chains are adsorbed perpendicular to the walls.
