MAGNETIC FIELD DISTRIBUTIONMEASUREMENT IN NMR

Peter Andris – Ivan Frollo

   Magnetic field distribution of the basic magnet is essential measurement in the Nuclear Magnetic Resonance (NMR). It is useful for the magnet homogeneity setting and also for many further parameters calculation. Magnetic field distribution is derived from the basic magnet inhomogeneity measurement. The simplest way of its measurement is processing the NMR data (signal from NMR experiment after the Fourier transform) for their phase is proportional to the inhomogeneity. Experimental measurement was performed and possible errors are indicated.
