This chapter introduces some main definitions and the general aspects in NMR spectrometry, formulates the theoretical basis of NMR and physical principles for the observation of NMR signals, and illustrates the application of NMR for different studies in solutions and the solid state. The following topics are discussed: detection of NMR signals by the continuous-wave and Fourier transformation (FT) techniques, NMR equipments (magnets and probes), NMR spectral parameters (chemical shift, spin-spin coupling) and their physical origins, and nuclear relaxation and relaxation mechanisms in liquids and solids. The second part of the chapter concerns various spectroscopic NMR experiments in liquids and solids, including some specific aspects such as zero-field NMR spectroscopy, experiments with dynamic nuclear polarization and imaging NMR. Finally this chapter provides the literature for further reading.
