The solute orientational order in a nematic binary solution by NMR

Abstract

The orientational order of a solute (monofluorobenzene) dispersed in a nematogenic solvent (p,p′‐dihexyloxyazoxybenzene) is examined by NMR as functions of temperature and composition of the binary solution over the nematic phase region. The order is found to be solely characterized by the reduced temperature whereby a correspondence rule between T and mole fraction is established, and the coexistence curve of the nematic and isotropic phases is shown to serve as the minimum equiorder profile.
