13C NMR Observation of Molecular Motions at the Smectic-A-Smectic-C (Smectic-C*) Transition in a Recemic (Chiral) Smectic Liquid Crystal

Properties near the nematic-smectic-A-smectic-C multicritical point present in binary liquid-crystal mixtures are reviewed. Recent dynamic Fréedericksz deformation and quasielastic light-scattering results are described and their relationship with data from X-ray scattering and static light scattering is discussed.

Field Behaviour

The information about liquid crystal phases that can be obtained by light scattering and by high-resolution X-ray scattering is reviewed. Results for the nematic-smectic A transition suggest the de Gennes-McMillan model is correct, but adequate theoretical solutions to the model remain elusive. Recent results on the smectic A to smectic C transition are presented that show unambiguously that it exhibits classic mean-field behaviour and this is explained by a Ginzburg criterion argument. Some preliminary results of a study of a nematic-smectic A transition in a lyotropic material are given and indicate similarity to thermotropic materials.
