Orientation in liquid crystal polymers

The same principle, but applied to UV spectra, has been exploited for measuring orientation in liquid crystal polymers by groups in Germany and the USSR. ... 

In summary, wide-angle X-ray scattering offers an almost unique opportunity to assess properly the molecular segmental orientation in liquid crystal polymers, by providing both orientational parameters and a structural model of the orienting unit. Furthermore, it is possible to obtain some information as to the level of local orientation, in contrast to the macroscopic or global orientation normally quoted. 

The reader is directed elsewhere for a more detailed discussion of the use of x-ray Scattering procedures to evaluate the level of preferred orientation in liquid crystal polymers [1].
