Pretranstional phenomena in phospholipid/water multilayers.

Abstract

We have measured the water order in monodomain phospholipid samples using 2H nuclear magnetic resonance (NMR) and analyzed the splittings in terms of critical exponents. Our data and the model developed to interpret them in terms of fluctuations provide an explanation of the puzzling sharp reduction of water order near the chain-ordering phase transition. The temperature range of the fluctuations is approximately the same as that observed for increased 22Na+ efflux from phospholipid vesicles.
