Definition from
Biology Dictionary:
It's a process used to find out information about a compound’s magnetic properties. It does so by recording the magnetic spectral patterns given off by the nuclei within a sample’s atoms. Using NMR, researchers can determine the molecular structure of a compound.
Example sentences:
Nuclear magnetic resonance (NMR) spectroscopy probes the local magnetic environment of a nucleus with non-zero magnetic moment in terms of its chemical shift (which depends on the amount of magnetic shielding and hence on its chemical environment) and line splitting, due to magnetic coupling to the nuclear spins of neighbouring atoms. (ScienceDirect)
NMR techniques are utilized in determining the changes on heat-treated foods. In this technique, change of water distribution and mobility in foods could be determined without damaging to food. Also, it is one of the techniques used to determine the level of melamine in foods. In addition, nuclear magnetic resonance spectroscopy is a good method to determine water holding capacity, intramuscular fat and total water content of meat. (Current Research in Nutrition and Food)
We perform 1H and 19F nuclear magnetic resonance spectroscopy at room temperature in magnetic fields below 50 mT. Using a solution of CsF in glycerol, we determine that 4 ± 2 × 1012 19F spins in a 1 pl volume can be detected with a signal-to-noise ratio of 3 in 1 s of integration. (nature communications)

spectroscopie de rezonanță magnetică nucleară
Definition from
Societății de Neurologie și Psihiatr:
Spectroscopia prin rezonanță magnetică, MRS, este o tehnică biochimică folosită pentru a identifica concentrația de metaboliți celulari diferiți în țesuturi. Originile MRS se află în subdisciplina fizicii intitulată spectroscopie de rezonanță magnetică nucleară (NMR), care a fost folosită încă din anii 1950 pentru identificarea momentelor magnetice nucleare ale radionucleilor. De la introducerea RMN în medicina clinică sub formă de imagistică prin rezonanță magnetică (RMN), s-au făcut multe îmbunătățiri pentru cuantificarea concentrațiilor metabolitului, mai degrabă decât pentru a oferi imagini anatomice.
Example sentences:
Spectroscopia de rezonanță magnetică nucleară (spectroscopia RMN) este o tehnică spectroscopică bazată pe fenomenul de rezonanță magnetică nucleară des folosită în chimie, chimie fizică, medicină nucleară, biofizică și inginerie nucleară pentru determinarea structurii diverșilor compuși chimici.
