摘要:
Dielectric measurements on four diols showing columnar hexagonal and micellar cubic phases were carried out. Besides the known fast local reorientation in theGHz-range, a new absorption in theMHz region was detected. This mechanism was interpreted as a collective motion of the molecules inside the micelles or cylindrical aggregates. The absorption was also found in the isotropic phase. Based upon the interpretation given, the molecular aggregates should also exist in the isotropic state. The electrical conductivity strongly supports the classification as inverse phases.
