NMR Line Shape Studies in a Nematic Liquid Crystal Slab

The director distribution function in different configuration of nematic liquid crystals which are confined in a slab is calculated by minimizing the distortion free energy. Using this function and the appropriate frequency distribution function, NMR line shape is determined in different thicknesses of the slab. By increasing the slab thickness, the maximum distortion in the centre of the slab is increased. This effect reveals in the broadening of NMR lines.
