Elastic incoherent neutron scattering of rotational and translational dynamics in liquid crystals

New theoretical approaches for the translational and rotational contributions to the elastic incoherent structure factor (EISF) of neutron scattering in mesomorphic systems are proposed. The influence of the molecular biaxiality and steric hindrance on the reorientational processes is considered. The numerical data for EISF are presented and discussed.
