Microscopic Aspects of the Nematic Phases

  • W. H. de Jeu
Part of the NATO ASI Series book series (NSSB, volume 290)


First a critical evaluation will be given of the structure and local order of molecules that typically give nematic behaviour. This allows the approximations made implicitly when real molecules are represented by simple rigid objects to be discussed. Microscopic order parameters will be defined starting from the orientational distribution function of the molecules. Connection will be made with macroscopic anisotropic properties that are often used to determine order parameters experimentally. In terms of intermolecular interactions the role of attractive forces and of excluded volume effects will be considered. The relevance of these molecular models will be discussed.
