Abstract

Some specific applications of NMR to lyotropic liquid crystals are reported on examples taken from studies in progress on sodium alky 1-phosphate/water systems. The reorientation dynamics of intersticial water is obtained from the splittings and relaxation rates of 1H, 2H and 17O. The molecular order parameters and alkyl chain conformation are derived from 2H quadrupolar splittings and interpreted in term of intermolecular interaction confining the molecules in restricted volumes. The rotational diffusion coefficients of surfactant molecules are obtained from the temperature and frequency dependences of the 31P longitudinal relaxation which depends on the chemical shift anisotropy and on the dipolar coupling with nearby protons.
