MEASURING MAGNETIC DIPOLE COUPLINGS IN ANISOTROPIC PHASES

A survey of experimental methods is presented that allow the measureme nt of magnetic dipole couplings by nuclear magnetic resonance spectros copy in liquid crystalline phases. Several techniques are employed, al one or in combination, to simplify and interpret the spectra arising f rom medium-size molecules in anisotropic phases. Among those, chemical substitution of protons by deuterium nuclei, multidimensional spectro scopy and rapid mechanical rotation of the sample.
