Abstract
H-2 NMR spectroscopy is employed to investigate the orientational order, mo lecular structure and phase transitions of the chiral smectic liquid crysta l 1-methylheptyl 4'-(4-n-decyloxybenzoyloxy)biphenyl-4-carboxylate (10B1M7) , showing smectic A, C* and J phases, as well as several sub-smectic C* pha ses. Two optically pure, differently deuteriated isotopomers have been purp osely synthesized and studied.
