A comparison is made between the KBr pellet and FT-IR/PAS spectra of a series of interlamellar-cation-exchanged montmorillonites. Spectra, of these clay minerals after adsorption of dimethyl methylphosphonate are also compared by the two spectroscopic methods. It is shown that the two infrared methods yield complementary spectral information, while FT-IR/PAS produces spectra with better definition of the adsorbate bands in all cases and superior reliability for observation of interlamellar ion-induced spectral shifts. Dimethyl methylphosphonate is shown to undergo interlamellar insertion, with bonding occurring directly through the P=O moiety to the cation of the clay mineral. The strength of the bonding varies with the charge density of the cation.
