RT Journal Article SR Electronic T1 Principles of Nuclear Magnetic Resonance JF Journal of Nuclear Medicine JO J Nucl Med FD Society of Nuclear Medicine SP 101 OP 111 VO 25 IS 1 A1 Koutcher, Jason A. A1 Burt, C. Tyler YR 1984 UL http://jnm.snmjournals.org/content/25/1/101.abstract AB 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.
