Structurally, liquid crystals are intermediate phases between the highly ordered crystal and the totally disordered liquid phase that combine the anisotropic physical properties of the former with the fluidity exhibited by the latter. Because of their partial order, the molecular structure of this condensed phase can only be modelled based on X-ray (and neutron) diffraction combined with, among other techniques, optical and thermal analyses. In this presentation we show the capability of X-ray diffraction methods to infer the detailed molecular structure of a Schiff base in its liquid crystal phase.
