NMR Spectroscopic Investigation of Intercalation Compounds of Organic Molecules and Sheet Silicates—p‐Xylene‐Hectorite and Related Systems

p‐Xylene and γ‐butyrolactone, taken up in the interlamellar spaces of the sheet silicate hectorite, were used to examine the possibilities offered by NMR spectroscopy as a method of studying such intercalation compounds. Using a pulsed FT‐NMR spectrometer, the degree of molecular freedom of an intercalated organic compound, the composition of mixtures, and even ketoenol equilibrium positions, can be determined.
