Nuclear Magnetic Resonance (NMR) ni nuceli (Nucleaire) yihariye ya spekitroscopi igera kure mubikorwa bya siyansi yumubiri, chimie ninganda. NMR ikoresha magnet nini (Magnetic) kugirango isuzume imiterere ya spin nucleique ya atome nuclei. Kimwe na spekitroscopi zose, NMR ikoresha igice cyimirasire yumuriro wa radiyo (radiyo yumurongo wa radiyo) kugirango iteze imbere inzibacyuho hagati yingufu za kirimbuzi (Resonance).

Muri iki gihe, NMR yahindutse ikoranabuhanga rinini kandi rikomeye ryisesengura ryabonye uburyo butandukanye mu bumenyi bwinshi bw’ubushakashatsi bwa siyansi, ubuvuzi, n’inganda zitandukanye. NMR igezweho ya sprosroscopi yagiye ishimangira ikoreshwa muri sisitemu ya biomolecular kandi igira uruhare runini mubuzima bwibinyabuzima. Hamwe niterambere muburyo bwuburyo bukoreshwa mubikoresho mumyaka 20 ishize, NMR yabaye imwe mubuhanga bukomeye kandi butandukanye bwa spekitroscopique yo gusesengura biomacromolecules

Magnet ya NMR twavuga ko igice cyingenzi cya ecran ya NMR. Magnet ya NMR ni kimwe mu bintu bihenze cyane bya sisitemu ya magnetiki resonance spectrometer. Ikoranabuhanga rya NMR ryateye imbere cyane kuva iterambere rya NMR. Imashini ya mbere ya NMR yari ibyuma byuma bihoraho cyangwa electromagneti itanga imirima ya magneti iri munsi ya 1.5 T. Uyu munsi, magnesi nyinshi za NMR nubwoko bwikirenga.
