- Nuclear Magnetic Resonance Spectroscopy (NMR)
- Additional fields of expertise
- Definition(s)
- 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. Biology Dictionary
- Example sentence(s)
- 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
by - 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
by - 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

- espectroscopia por resonancia magnética nuclear (RMN)
- Additional fields of expertise
- Definition(s)
- Esta técnica utiliza ondas de radio que se emiten de forma prácticamente continua en lugar de emitirse en forma de pulsos, como en la resonancia magnética nuclear (RMN) convencional. La espectroscopia por resonancia magnética nuclear se utiliza para detectar trastornos cerebrales, como epilepsia, enfermedad de Alzheimer y tumores y abscesos cerebrales. Este método puede distinguir entre el tejido muerto dentro de un absceso y la presencia de células multiplicándose dentro de un tumor. Manual MSD - by María C Turri

- Kernspinresonanzspektroskopie
- Additional fields of expertise
- Definition(s)
- Kernspinresonanzspektroskopie, Magnetresonanzspektroskopie, Magnetkernspinresonanzspektroskopie, NMR-Spektroskopie, E nuclear magnetic resonance spectroscopy, eine zur Strukturaufklärung von organischen und metallorganischen, seltener von anorganischen Verbindungen angewandte Methode, die den Eigendrehimpuls (Spin, siehe Zusatzinfo) von Atomkernen misst. Dabei wird die Verbindung einem nicht-oszillierenden magnetischen Feld ausgesetzt. Die charakteristische Kernresonanz bestimmter Atome oder funktioneller Gruppen in diesem Feld wird durch benachbarte Atome oder Gruppen verändert, wodurch Rückschlüsse auf die Molekülstruktur gezogen werden können Spektrum - by Steffen Walter
- Example sentence(s)
- Die Kernspinresonanzspektroskopie (NMR-Spektroskopie von englisch nuclear magnetic resonance) ist eine spektroskopische Methode zur Untersuchung der elektronischen Umgebung einzelner Atome und der Wechselwirkungen mit den Nachbaratomen. - Wikipedia
by Steffen Walter - Innerhalb der letzten fünfzig Jahre hat sich die Kernspinresonanzspektroskopie (NMR) zu einer führenden Methode zur Bestimmung der Struktur organischer Verbindungen auf molekularer Ebene entwickelt. - Martin-Luther-Univ. Halle-Wittenberg
by Steffen Walter - Die Kernspinresonanzspektroskopie (NMR-Spektroskopie von engl. nuclear magnetic resonance) ist eine spektroskopische Methode, welche die Untersuchung der elektronischen Umgebung einzelner Atome und der Wechselwirkungen mit seinen Nachbaratomen erlaubt. - Analytik.de

- Tuumamagnetresonantsspektroskoopia
- Additional fields of expertise
- Definition(s)
- Tuumamagnetresonantsspektroskoopia (lühend TMR-spektroskoopia) on raadiosagedusdiapasoonis töötav spektroskoopia liik, mille puhul spektri saamiseks rakendatakse tugevasse püsimagnetvälja (4...24 T) viidud aine aatomituumade ergastamist ja sellele järgneva kiirguse registreerimist. Wikipedia - by Lennart Luhtaru
- Example sentence(s)
- Eestis kasutatakse tuumamagnetresonantsspektromeetriat näiteks Tartu Ülikoolis, Keemilise ja Bioloogilise Füüsika Instituudis ja Tallinna Tehnikaülikooli keemiainstituudis. - Wikipedia

- Spektroskopia e Rezonancës Magnetike Bërthamore
- Additional fields of expertise
- Definition(s)
- Spektroskopia e Rezonancës Magnetike Bërthamore është një teknikë sasiore për analizimin e materialeve për të përcaktuar përbërësit kimikë organikë të një mostre. EUROLAP - by Denis Haska
- Example sentence(s)
- Në fiziken atomike, molekulare dhe fiziken e trupit te ngurte, gradienti i fushës elektrike (GFE) mat normën e ndryshimit të fushës elektrike në një bërthamë atomike të gjeneruar nga shpërndarja e ngarkesës se elektronit dhe bërthamave të tjera. GFE çiftohet me momenti quadrupol elektrik bërthamor të bërthamave quadripolare (ato me numër spini më të madh se sa një e gjysmë) për të gjeneruar një efekt që mund të matet duke përdorur disa metoda spectroskopike, të tilla si rezonanca magnetike bërthamore (RMB), rezonanca paramagnetike e elektronit (EPR, ESR), rezonancë bërthamore quadripole (NQR), spektroskopia e Mössbauer ose korrelacion këndore te trazuar (PAC). - Wikipedia
by Denis Haska - Ekspertët tanë fitojnë njohuri për përbërjen e materialeve të ricikluara duke përdorur një sërë teknikash të tilla si rezonancë magnetike bërthamore (NMR), GPC, ICP dhe XRF, ose riciklohen ose si produkt përfundimtar, sidomos në prodhimin e materialeve me bazë poliestër. - Eurolab
