ABSTRACT
Nuclear magnetic resonance (NMR) spectroscopy has been used successfully in the study of clay minerals and clay organic interactions, providing information on both structural and dynamic aspects. This chapter is concerned with clayorganic interactions, but due to the complexity of these reactions in which are involved simultaneously the silicate substrate, inorganic cations, water and the organic species, references to the NMR study of phyllosilicate structure, localiza tion, and mobility of exchangeable inorganic cations and water have also been included.
