Electric field NMR
From Wikipedia, the free encyclopedia
Electric field NMR (EFNMR) spectroscopy differs from conventional NMR in that a sample containing suitable nuclei is polarised by a strong dc electric field instead of a constant magnetic field. The nuclei are stimulated (perturbed) by means of an alternating magnetic field, generated by passing an alternating current through a set of coils. The resulting magnetic resonance signal is small, and is typically sensed using a second set of coils and an amplifier.
Note that the same acronym is used for Earth's field NMR.
