Nuclear Magnetic Resonance (NMR) takamaiman nuceli (Nuclear) ƙayyadaddun spectroscopy ne wanda ke da aikace-aikace mai nisa a cikin ilimin kimiyyar jiki, sunadarai da masana'antu. NMR yana amfani da babban maganadisu (Magnetic) don bincika ainihin kaddarorin ƙwayoyin atomic. Kamar duk spectroscopies, NMR yana amfani da wani ɓangaren na'urar hasken lantarki (raƙuman mitar rediyo) don haɓaka sauye-sauye tsakanin matakan makamashin nukiliya (Resonance).

A yau, NMR ya zama fasaha mai ƙwarewa da ƙarfi wanda ya samo aikace-aikace iri-iri a yawancin nau'o'in binciken kimiyya, magani, da masana'antu daban-daban. NMR spectroscopy na zamani yana ƙarfafa aikace-aikacen a cikin tsarin biomolecular kuma yana taka muhimmiyar rawa a cikin ilimin halitta. Tare da ci gaba a cikin hanyoyin biyu da kayan aiki a cikin shekaru ashirin da suka gabata, NMR ya zama ɗaya daga cikin mafi ƙarfi da fasaha na spectroscopic don nazarin biomacromolecules.

Maganar magana ta NMR ita ce mafi mahimmancin sashin sikirin NMR. NMR maganadisu yana ɗaya daga cikin mafi tsada abubuwan da ake amfani da su na tsarin siginar maganadisu na maganadisu. Fasahar maganadisu ta NMR ta samo asali sosai tun lokacin haɓakar NMR. Na farko NMR maganadiso kasance baƙin ƙarfe core dindindin ko electromagnets samar da maganadiso kasa da 1.5 T. A yau, yawancin NMR maganadiso ne na superconducting nau'i.
