Abstract

Rapid lateral diffusion of phospholipid molecules in multilamellar dispersions is shown to prevent the observation, in powder pattern spectra, of the orientation dependence of ²H nuclear magnetic spin-lattice relaxation. The spin-lattice relaxation rate is found to have a frequency dependence suggestive of collective director fluctuations.
