The authors describe an alternative approach to signal acquisition in nuclear magnetic resonance and demonstrate this by measuring the free induction decay signal from a sample of glycerine. Traditionally, these systems have operated using pulse radio frequency excitation and magnetic (inductive) readout. This approach identifies the previously unmeasured electric field signal associated with the precessing nuclear spins and provides an alternative capacitive (noninductive) readout. The possible advantages which may accrue from this technique include a reduction in the dead time and the cross coupling between the transmitter and the receiver, a simpler receiver implementation, and an inherently high spatial resolution.

Additional Information: Experimental work by myself and student, funded as part of EPSRC Basic Technology project (GR/R87550/01). This reports the first observation of electric field readout in a nuclear magnetic resonance system. Technique forms the subject of patent 0602229.7 'Electric potential sensor for use in the detection of nuclear magnetic resonance signals', filed 03/02/2006. As a result, JEOL (UK) Ltd supplied a letter of support for the EPSRC translation grant (EP/E042864/1) and have asked to be kept informed of developments (Dr. P. Meadows, I was invited to present this work to Siemens Magnet Technology Ltd (Dr. M. Lakrimi,
