Abstract
Measurements of dielectric dispersion have been carried out on two liquid crystal compounds 8422[2F3] and 8O23[7F8-], showing non-layer-shrinkage (NLS) behavior through the smectic-A(Sm-A)-smectic-C (Sm-C) transition. The critical exponent determined from the data lies 1.5-1.9 for 8422[2F3], and 1.1-1.2 for 8O23[7F8-]. These results indicate that the Sm-A-Sm-C transition with NLS behavior can exhibit quasi two-dimensional Ising critical behavior under a certain condition.
