Microscopic Organization and Tilt angle in Smectic A and Chiral Smectic C* Phases: Characterization and Orientational Order by 2H-NMR and Electric Polarization Measurements

’H-NMR spectroscopy is employed to investigate the orientational order, tilt angle and layers organization of the chiral smectic liquid crystal (-)-(S)-[4-(2-methylbutyloxy carbonyl) phe- nyl] 4-n-heptyl-biphenyl carboxylate-d8 (MBHB-d,) in the magnetic field. The electrooptical behaviour of this material has a150 been investigated. The results from these two different techniques show the importance of molecular conformation for the electric and structural properties of this mesogen.
