We are particularly grateful to Joachim and Anna Seehgf or makmg avllable the selectively deuterated samples used III &us study. Our colleagues Myer Bloom, Ulrich Riberlen, Ken Jeffrey, and Ken Packer have provided numerous stimulating comments and dacus-s~ons. lIus work was supported by the Natural Science and Engmeenng Research Council of Canada (JHD) and by the Cystic Fibrosis Foundation (MFB).

N2 - 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.
