08218 IUPAC Gold Book - nuclear magnetic resonance spectroscopy 10.1351/goldbook.08218 08218 current initialism: NMR 1 Measurement principle of spectroscopy to measure the precession of magnetic moments placed in a magnetic induction based on absorption of electromagnetic radiation of a specific frequency by an atomic nucleus. Nuclei having a suitable magnetic moment include \(\ce{^{1}H}\), \(\ce{^{13}C}\), \(\ce{^{15}N}\), \(\ce{^{19}F}\), \(\ce{^{31}P}\). The technique is used as a method of determining structure of organic molecules, or as a mechanism for quantification. electromagnetic radiation https://goldbook.iupac.org//terms/view/08242 PAC, 2021, 93, 647.
