✦ Synopsis
ExperimentaI results of an investigation of the proton spin-lattice relaxation in a weU-+oxvn homologous series exhiiiting smectic polymorphism, are presented. Bxphaatioas for strik& features of Tr and TrB dependences on temperature, frequency and molecular orientation in terms of mokcuh motions are proposed.

## Abstract Proton NMR relaxation measurements have been carried out in the mixed system of antiferroelectric (AFE) betaine phosphate (BP) and ferroelectric (FE) glycine phosphite (GPI), BP~__x__~GPI~(1−__x__)~, at 11.4 and 23.3 MHz from 300 to 100 K for __x__ = 0.3, 0.4, 0.5, 0.6, 0.7 and 0.8. The
