An application of field gradient attaches a spatial information in NMR signal, therefore, it can produce a spatial distribution of nuclei, that is, NMR imaging [1,2]. When two field gradients for the diphase and rephrase applied, the NMR signal decays due to the displacement of nucleus during the time between two field gradients [3,4]. This gives the diffusion coefficient for Fickian diffusion in free space and the space size for a spatially restricted diffusion [5]. Recently, the field gradient is used for the selection of desired coherence pathway by rephasing the desired coherence and dephasing the undesired coherence [6]. In this chapter, these three important uses of field gradient are described.
