Pictorial representation of the meaning of the function in the case the solvent is HAB, the solute is DCB and their centers of mass are separated by a distance along the director : is the area, enclosed by the dotted line, excluded by the solute molecule to the solvent molecule.
The molecular structure of HAB, the solvent, and the solutes (DCB and NFT). Shown are the HAB principal axis with respect to which the solvent orientational order parameter is defined, as well as the hydrogen atom numbering and the molecular frame of reference of the two solutes.
Calculated and experimental spectra of NFT in HAB at .
Example of the behavior of as a function of for the two solute-solvent pairs. The curves shown correspond to the case , with and as the solute Euler angles3, and .
Experimental vs fitted Saupe ordering matrices across the temperature for DCB and NFT: circles correspond to of DCB, squares to of DCB, triangles up to of NFT, triangles down to of NFT, full symbols to the experimental data, and empty symbols to the fitted data.
