Propionic Acid Nuklia Magnetic Resonance (NMR) Spectroscopy
Jiri igwe nyocha ihe mmetụta nuklia maka nchọpụta acid propionic. Site na iji nyocha nke nhazi propionic acid na ngwaahịa mmepụta kemịkalụ dịka ihe atụ, buru ụzọ kwadebe ihe nlele ahụ ka ọ bụrụ ihe ngwọta nke ntinye kwesịrị ekwesị, na-ejikarị ihe ndị na-eme ka ọ dị nro dịka chloroform deuterated iji zere nnyonye anya site na oke ihe mgbaze na oke ihe nlele ahụ. Tinye ọkpọkọ NMR nwere ihe ngwọta ihe nlele ahụ n'ime nyocha nke spectrometer NMR. Ngwaọrụ ahụ na-ewepụta pulses rediofrequency iji kpalite mgbanwe ọkwa ike nuklia na atọm nke molekul ihe nlele ahụ. Nuclei na gburugburu kemịkalụ dị iche iche na-amịkọrọ ma na-ewepụta akara rediofrequency dị iche iche, na-ebute oke dị iche na spectrum NMR. Site na inyocha gburugburu kemịkalụ nke atọm hydrogen ọ bụla na molekul propionic acid, yana ozi dịka ọnọdụ kacha elu (mgbanwe kemịkalụ) na nkewa kacha elu (njikọ na-adịgide adịgide), enwere ike ịkwado nhazi nke propionic acid. Enwere ike ime nyocha ọnụọgụ nke ọdịnaya ya ruo n'ókè ụfọdụ. Agbanyeghị, spectroscopy NMR anaghị akọwacha nke ọma maka nyocha ọnụọgụ ma e jiri ya tụnyere ụzọ ndị ọzọ, mana ọ na-enye uru pụrụ iche maka nyocha nhazi.
