Self-Diffusion and Molecular Order in Lyotropic Liquid Crystals

The translational self-diffusion coefficients of the H₂O molecules in the water channels of both hexagonal and lamellar lyotropic liquid crystals have been measured by the variable field-gradient proton spin-echo method, and the temperature dependence of the ordering of D₂O and H₂O molecules was studied by quadrupole perturbed deuteron NMR and proton spin-lattice relaxation measurements.
