Simulations of flow-induced director structures in nematic liquid crystalsthrough Leslie-Ericksen equations. II. Interpretation of NMR experiments in liquid crystal polymers

Computationally exact and approximate solutions of the Leslie-Ericksen equa tions for nematic liquid crystals in two dimensions are employed to calcula te director distributions in cylindrical samples, rotating under the influe nce of a magnetic field. In particular, the time evolution of systems prepa red initially in metastable states with respect to the magnetic field is in vestigated, and calculated director distributions are used to interpret rhe o-NMR experiments in nematic liquid crystal polymers.
