Activation Parameters of Self-Diffusion of Aromatic Chiral Molecules in External Magnetic Fields

The mobility of aromatic chiral molecules 1-phenylethanol and 1-phenyl-1-propanol in liquids was studied by 1H NMR spectroscopy depending on the strength of the external magnetic field, temperature, and concentration ratio of enantiomers. The data obtained were analyzed using Arrhenius law. The acti...

Description
Summary:The mobility of aromatic chiral molecules 1-phenylethanol and 1-phenyl-1-propanol in liquids was studied by 1H NMR spectroscopy depending on the strength of the external magnetic field, temperature, and concentration ratio of enantiomers. The data obtained were analyzed using Arrhenius law. The activation parameters were found to depend on the applied field. This effect is caused by the induced magnetic moments in aromatic molecules. The use of strong magnetic fields seems to be promising for investigation of intermolecular interactions of chiral molecules.
