Abstract
In the deuteron magnetic resonance of water in the dipalmitoyl-phosphatidylcholine-D 2 O system, a weak doublet spectrum having a splitting of 1.1±0.1 kHz was observed separately from the signals of all other water molecules in the liquid crystalline phase. This spectrum was ascribed to water molecules bound tightly to the phosphate group of the lipid (the water in the first hydration shell). The theoretical calculations for the splitting were carried out on the basis that the tightly bound water molecules reorient as a whole around the bilayer normal together with the head group of the lipid molecule and undergo rapid exchange between the hydration sites in the first shell. The calculated value of the splitting is in good agreement with the experimental value.
