DYNAMICS OF AMPHIPHILIC SYSTEMS STUDIED USING NMR RELAXATION AND PULSED-FIELD GRADIENT EXPERIMENTS

NMR continues to be of importance in experimental studies of surfactan t systems, NMR-based diffusion studies play a central role as a routin e tool in the investigation of the solution structure of microemulsion s and related systems. Recently, we have also seen that the scope of t he method has widened, as it is now being applied to liquid crystals, vesicles and emulsions, as well as to the question of the rheological properties of surfactant solutions. NMR relaxation studies - which ove r the years have been applied, and continue to be applied, to isotropi c surfactant systems - are now also increasingly applied to anisotropi c liquid crystalline systems. Finally, during the past couple of years , we have seen the first applications of modern multi-dimensional NMR techniques to surfactant systems.
