Head‐group deuterated 1,2‐dimyristoyl‐ sn ‐glycero‐3‐phosphorylserine (DMPS) was synthesized. 2 H NMR spectra reflect the ionic strength‐dependent polymorphism of DMPS aqueous dispersions. Results obtained with pure DMPS and mixed bilayers with phosphatidylcholine or phosphatidylethanolamine at various NaCl or LiCl concentrations indicate that interactions with Na + and Li + have very different effects upon the head‐group quadrupole splittings.
