摘要：

Li-7 and Na-23 NMR spectra of clay suspensions in water have shown how the smectite structure and the nature of alkali counterions modulate the quadrupolar interaction. These probes, together with C-13 and H-2 nuclei, have been also used to study the interaction of dodecyldimenthylamine oxide with laponite and differently charged saponites dispersed in surfactant solutions.
