Proton, deuterium and carbon magnetic resonance techniques have been widely used to study the hydrocarbon chain region of model bilayer systems and biological membranes (for a review see [l]). More recently, phosphorus magnetic resonance (31P NMR) has been introduced to study the polar headgroup region of membranes [2-71. In this communication we show how 31P NMR can define an order parameter for the phosphate headgroup in model and biological membranes. In addition, in oriented systems the 31P NMR spectrum can provide information on the orientation of the membrane.
