I-Propionic Acid Nuclear Magnetic Resonance (NMR) Spectroscopy
Sebenzisa i-nuclear magnetic resonance spectrometer ukuze ufumane i-propionic acid. Ukuthatha uhlalutyo lwesakhiwo se-propionic acid kwiimveliso zokwenziwa kweekhemikhali njengomzekelo, qala ulungiselele isampuli ibe sisisombululo esifanelekileyo, ngokuqhelekileyo usebenzisa ii-reagents ezi-deuterated ezifana ne-deuterated chloroform ukuze uphephe ukuphazamiseka kwi-solvent peak kwi-sample peak. Beka ityhubhu ye-NMR equlethe isisombululo sesampuli kwi-probe ye-NMR spectrometer. Esi sixhobo sikhupha ii-radiofrequency pulses ukuze sibangele utshintsho lwamandla enyukliya kwiiathom zeemolekyuli zesampuli. Ii-Nuclei kwiindawo ezahlukeneyo zeekhemikhali zifunxa kwaye zikhuphe imiqondiso ye-radiofrequency ngokwahlukileyo, nto leyo ebangela iincopho ezahlukeneyo kwi-NMR spectrum. Ngokuhlalutya imeko-bume yeekhemikhali ye-athomu nganye ye-hydrogen kwi-propionic acid molecule, kunye nolwazi olufana nendawo yencopho (ukutshintsha kweekhemikhali) kunye nokwahlukana kwencopho (i-coupling constant), ulwakhiwo lwe-propionic acid lunokuqinisekiswa. Uhlalutyo lobungakanani bomxholo walo lunokwenziwa ukuya kwinqanaba elithile. Nangona kunjalo, i-NMR spectroscopy ngokubanzi ayichanekanga kangako kuhlalutyo lobungakanani xa ithelekiswa nezinye iindlela, kodwa inika iingenelo ezikhethekileyo kuhlalutyo lwesakhiwo.
