Ua raws li qhov no hauv kev xav, dab tsi yog qhov siab tshaj hauv NMR?

A ncov ntawm kev hloov tshuaj lom neeg ntawm, hais, 2.0 txhais tau tias qhov hydrogen atoms uas ua rau ntawd ncov xav tau ib qho chaw sib nqus ob lab tsawg dua li qhov xav tau los ntawm TMS los tsim resonance. A ncov ntawm kev hloov tshuaj lom neeg ntawm 2.0 tau hais tias yog downfield ntawm TMS. Ntxiv mus rau sab laug a ncov yog, qhov downfield ntau nws yog.

Tsis tas li ntawd, muaj pes tsawg NMR signals muaj? peb

Kuj nug, NMR ntsuas dab tsi?

Nuclear Sib Nqus Resonance ( NMR ) spectroscopy yog cov 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 nrog rau nws cov qauv molecular. Piv txwv li, NMR tuaj yeem txheeb xyuas cov khoom sib xyaw uas muaj cov khoom sib xyaw ua ke.

Kev hloov tshuaj lom neeg hauv NMR yog dab tsi?

Los ntawm Wikipedia, dawb encyclopedia. Hauv nuclear magnetic resonance ( NMR ) spectroscopy, ua tshuaj hloov pauv yog lub resonant zaus ntawm ib tug nucleus txheeb ze rau tus qauv nyob rau hauv ib tug magnetic teb. Feem ntau txoj hauj lwm thiab tus naj npawb ntawm tshuaj hloov pauv yog kuaj ntawm cov qauv ntawm ib tug molecule.
