A Study of Magnetic Susceptibility of NMR Samples in a Time Dependent Longitudinal Field

Abstract:

The paper mainly focuses on the possibility of realizing the NMR spectroscopy in a non-static external field. The behaviour of magnetic moment under a time-dependent magnetic longitudinal field is much different from that one under a static magnetic longitudinal field, because the magnetic susceptibility is a more complicated complex when both of transverse magnetic field and longitudinal field are time dependent. In this paper, we calculate the magnetic susceptibility of the water and give an analysis of the effect on the magnetic susceptibility in a time dependent longitudinal field and RF frequency.
