Abstract

The anisotropic motion and magnetic relaxation of small molecules in ordered fluids and liquid crystals are discussed. The molecules concerned are those with non-zero orientation factor, considerable local rotational diffusion and rapid internal rotation. Fourier intensities and relaxation times are calculated and expressed in terms of the orientation factor, the rotational correlation times, and the angle between the major axis and the vector of a dipolar pair or a quadrupolar axis. Special cases of molecules with and without internal rotation are considered. Examples of deuteron relaxation of CDCl3 in a thermotropic liquid crystal and in lipid vesicles, and C6D6 in lipid vesicles and biological membranes are discussed.
