Abstract
2H-NMR spectroscopy is employed to investigate the orientational order in the neinutic and smectic A, B, and G phases formed by 4-(2-methylbutyl)phenyl-4′n-heptylbiphenyl-4-car-boxylate (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 Quad-rupo'. ar relaxation times with the rotational diffusion model.Keywords
