Resonance na Magnetic na Nukiliya (NMR) na Propionic Acid
Yi amfani da na'urar auna karfin maganadisu ta nukiliya don gano sinadarin propionic acid. Idan aka ɗauki nazarin tsarin propionic acid a cikin samfuran hada sinadarai a matsayin misali, da farko a shirya samfurin a cikin wani bayani mai dacewa, yawanci ana amfani da sinadaran deuterated kamar deuterated chloroform don guje wa tsangwama daga saman sinadarin solvent akan saman samfurin. Sanya bututun NMR wanda ke ɗauke da maganin samfurin a cikin binciken na'urar auna NMR. Kayan aikin yana fitar da bugun rediyo don haifar da sauye-sauyen matakin makamashin nukiliya a cikin ƙwayoyin halittar samfurin. Nuclei a cikin mahalli daban-daban na sinadarai suna sha da fitar da siginar mitar rediyo daban-daban, wanda ke haifar da kololuwa daban-daban a cikin bakan NMR. Ta hanyar nazarin yanayin sinadarai na kowane ƙwayar hydrogen a cikin ƙwayar propionic acid, tare da bayanai kamar matsayin kololuwa (canjin sinadarai) da rabuwar kololuwa (daidaitaccen haɗin kai), ana iya tabbatar da tsarin propionic acid.
