Biaxial orientation representation

Fig. 54. Diagrammatic representation of a. random, b. uniaxial and c. biaxial orientation (in either case viewed in two directions perpendicular to each other, the direction of orientation included).

Biaxial nematic or Sa elastomers lack rotational symmetry around their molecular long axes and the orientation of the three axes is described by the additional minor director m. A third director I is thereby automatically defined. Figure 15 gives a schematic representation of a uniaxial and biaxial nematic phase. The orientation methods discussed in the previous section yield polydomains with respect to the... 

The Cartesian tensor representation can be extended to describe the orientational ordering of biaxial molecules in biaxial phases by introducing [6] a fourth rank ordering tensor ... 

The orientational ordering in a biaxial nematic phase can also be described using a Cartesian representation of the order paramaas. At the second rank level this description is provided by the supermatrix...
