The basic principles of nuclear magnetic resonance (NMR) are discussed. The concepts presented include a qualitative quantum-mechanical approach to NMR spectroscopy and a classical-mechanical approach to time-dependent NMR phenomena (relaxation effects). The spectroscopic concepts discussed include absorption of radiation by matter, spin and energy quantization , chemical shift, and spin-spin splitting. The time-dependent phenomena include the concepts of T1 and T2, the spin-lattice and spin-spin relaxation time, and Fourier-transform NMR spectroscopy.
本文讨论了核磁共振（NMR）的基本原理。所介绍的概念包括核磁共振光谱的定性量子力学方法以及与时间相关的核磁共振现象（弛豫效应）的经典力学方法。所讨论的光谱学概念包括物质对辐射的吸收、自旋和能量量子化、化学位移以及自旋-自旋分裂。与时间相关的现象包括T1和T2的概念、自旋-晶格和自旋-自旋弛豫时间以及傅里叶变换核磁共振光谱。
