Hexamethylbenzene (HMB) adsorbed into the supercages of zeolite Na-Y is characterized by thermogravimetric analyses, proton NMR, ^(13)C NMR, proton multiple-quantum NMR, and UV, reflectance and emission spectroscopies. Room temperature, proton multiple-quantum NMR results reveal that the intracrystalline distribution of HMB is primarily pairwise at bulk concentrations of 0.5, 1.0, and 2.0 molecules per supercage. Results from emission spectroscopy suggest that the HMB pairs are uniformly dispersed among the intracrystalline supercages of Na-Y.
