Propionic Acid Nuclear Magnetic Resonance (NMR Spectroscopy)
Siv lub tshuab ntsuas hluav taws xob nuclear magnetic resonance spectrometer rau kev nrhiav propionic acid. Piv txwv li, kev tshuaj xyuas cov qauv propionic acid hauv cov khoom siv tshuaj ua ke, ua ntej npaj cov qauv mus rau hauv cov tshuaj uas muaj qhov concentration tsim nyog, feem ntau siv cov tshuaj reagents deuterated xws li deuterated chloroform kom tsis txhob muaj kev cuam tshuam los ntawm lub ncov solvent ntawm lub ncov qauv. Muab lub raj NMR uas muaj cov tshuaj qauv rau hauv qhov probe ntawm NMR spectrometer. Lub cuab yeej tso tawm cov pulses radiofrequency los ua kom muaj kev hloov pauv ntawm lub zog nuclear hauv cov atoms ntawm cov qauv molecules. Cov nuclei hauv cov chaw sib txawv ntawm cov tshuaj nqus thiab tso tawm cov teeb liab radiofrequency sib txawv, ua rau muaj cov ncov sib txawv hauv NMR spectrum. Los ntawm kev tshuaj xyuas cov tshuaj ib puag ncig ntawm txhua lub hydrogen atom hauv cov propionic acid molecule, nrog rau cov ntaub ntawv xws li qhov chaw siab tshaj plaws (kev hloov pauv tshuaj) thiab qhov siab tshaj plaws (kev sib cais tas mus li), cov qauv ntawm propionic acid tuaj yeem lees paub. Kev tshuaj xyuas ntau ntawm nws cov ntsiab lus kuj tuaj yeem ua tau rau qee qhov. Txawm li cas los xij, NMR spectroscopy feem ntau tsis meej rau kev tshuaj xyuas ntau piv rau lwm txoj hauv kev, tab sis nws muaj cov txiaj ntsig tshwj xeeb rau kev tshuaj xyuas cov qauv.
