The adsorption of benzenoid aromatic compounds on porous silica has been studied by 13 C and 19 F NMR and by BET measurements. Small chemical shifts between the resonances of methyl groups or fluorine substituents in the microcrystalline bulk material and the adsorbed species can be used to monitor
