✦ Synopsis

Both pulse and C.W. proton n.m.r, have been used for fmther 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 --NMe3 group is relatively mobile.

P.m.r. measurements have been made on macroscopically ordered samples of the smectic mesophase in two 1-monoglyceride + water systems and the 1-amino-octane + water system. Three doublets have been observed, one from hydroxyl protons, and the remaining two from methylene protons in two sections of t
