摘要：

Nuclear magnetic resonance spectra are blind to chirality unless the environment discriminates D and L enantiomers. However, a nuclear magnetic moment in the x-direction combined with the strong magnetic field B-z((0)) induces, through an odd-parity coupling in a freely tumbling chiral molecule, an electric dipole moment in the y-direction. Estimates of the rotating electric polarization at the NMR frequency following a pi/2 pulse indicate that it should be detectable in favourable cases, foreshadowing a new dimension for the NMR spectroscopy of chiral molecules.
