Abstract

2H-NMR spectroscopy is employed to investigate the orientational order in the nematic and smectic A, B, and G phases formed by 4-(2-methylbutyl)phenyl-4′n-heptylbiphenyl-4-carboxylate (7BEF5). The dynamics of the aromatic molecular core is studied in a temperature interval including the SA - SB transition, by the analysis of the deuterium Zeeman and Quadrupolar relaxation times with the rotational diffusion model.
