摘要：

In this work we present the results of the complex dielectric constant (epsilon', epsilon '') and of the apparent tilt angle, concerning a new chiral compound exhibiting several smectic mesophases. Four polar smectic C* phases were identified: S-CA*, S-CFI*, S-C* and S-C alpha*. An analysis of the relaxation frequency of the system and the distribution of the relaxation times is also presented.
