Abstract
We introduce the description of translational, orientational and internal order parameters in liquid crystals. We give a systematic approach to the identification of the relevant parameters as expansion coefficients of the singlet distribution function in a suitable basis set. The construction of approximate distributions from a limited set of order parameters using the maximum entropy principle is discussed. We treat in detail order parameters and distribution functions for three cases: rigid molecules with cylindrical or biaxial symmetry and non-rigid molecules with one internal rotor dissolved in various mesophases.
