Proton n.m.r. relaxation study of mobility in lipid water systems

Research output: Contribution to journalArticlepeer-review


Both pulse and C.W. proton n.m.r. have been used for further study of the mobility of the hydrocarbon chains and headgroups in some smectic liquid crystalline phases. It is shown that dipolar broadening is responsible for the observed proton linewidths in these systems, in the frequency range 10-40 MHz. In lecithins in the liquid crystalline phase, the -N+NMe3 group is relatively mobile.
