摘要
The use of NMR spectroscopy of molecules oriented in liquid-crystalline media to study solvent-solute and solute-solute interactions in pi-systems such as benzene-chloroform and in charge transfer complexes, for example pyridine-iodine, is illustrated. Changes in molecular order and chemical shifts as a result of complexation are employed in such studies. The extraordinary symmetry of C60 has also been investigated by using a mixture of liquid crystals of opposite diamagnetic anisotropies indicating, thereby, negligible solvent-solute/solute-solute interactions.
