摘要：

Dielectric measurements on two different samples formed by banana-shaped molecules and showing a B-1 phase were carried out. Three relaxation ranges were detected: a very fast intramolecular motion, the fast reorientation about the long axes and a slow collective process. The data are discussed in relation to known X-ray investigations and dielectric results for homologous samples showing the B-2 state. The main difference between B-1 and B-2 is that in B-1 no evidence for ferroelectric order in the short range was detected.
