Nuclear magnetic resonance spectroscopy yog dav siv los txiav txim cov qauv ntawm cov organic molecules nyob rau hauv kev daws thiab kawm molecular physics, crystals thiab non-crystalline cov ntaub ntawv. NMR tseem niaj hnub siv nyob rau hauv cov txheej txheem kho mob siab heev, xws li hauv magnetic resonance imaging (MRI).

Kuj nug, NMR siv rau dab tsi?

Nuclear Sib Nqus Resonance ( NMR ) spectroscopy yog ib qho txheej txheem analytical chemistry siv hauv kev tswj kom zoo thiab reserach rau kev txiav txim siab cov ntsiab lus thiab purity ntawm tus qauv raws li nws cov qauv molecular. Piv txwv li, NMR tuaj yeem txheeb xyuas cov khoom sib xyaw uas muaj cov khoom sib xyaw ua ke.

NMR ua haujlwm li cas?

Nuclear magnetic resonance, NMR , yog lub cev tshwm sim ntawm resonance hloov pauv ntawm qib sib nqus zog, tshwm sim thaum atomic nuclei rau hauv ib qho chaw sib nqus sab nraud thiab siv hluav taws xob hluav taws xob nrog cov zaus tshwj xeeb. Los ntawm kev kuaj pom cov cim nqus, ib tus tuaj yeem tau txais NMR spectrum.

Puas yog NMR thiab MRI tib yam?

Sib nqus resonance imaging. MRI tsis koom nrog X-rays lossis kev siv hluav taws xob ionizing, uas txawv ntawm CT thiab PET scans. MRI yog ib daim ntawv thov kev kho mob ntawm nuclear magnetic resonance ( NMR ). NMR kuj tseem siv tau rau kev yees duab hauv lwm yam NMR kev siv, xws li NMR spectroscopy.
