Preparation and investigations of thermotropic liquid crystals labelled by stable isotope, II. Synthesis and 2H NMR spectroscopic investigation of [4-(2-methyIbutyl)phenyl] 4'-n-heptyl-biphenylcarboxylate-dig (7BEF5-dis) and its isotopomer, 7BEF5-d6 The thermotropic liquid crystal 4-[(2-methyl-butyl)-phenyl]-4'-n-heptyl-biphenyl-carboxylate (7BEF5) and its isotopomers as 7BEF5-di8, and VBEFS-ds were prepared for 2H NMR investigations. These compounds exhibit nematic, smectic A, B and G phases, in which the labelled segments of the molecules were investigated in magnetic field.
