Te Matawai Aukume Matū (NMR) o te Waikawa Propionic
Whakamahia he ine aukume aukume karihi hei kimi i te waikawa propionic. Hei tauira, mā te tātari i te hanganga waikawa propionic i roto i ngā hua hanga matū, tuatahi whakaritea te tauira ki roto i tētahi otinga he kukū tika, mā te whakamahi i ngā matū kua whakakorengia pērā i te chloroform kua whakakorengia hei karo i te pokanoa mai i te tihi whakarewa ki te tihi tauira. Whakanohoia te ngongo NMR kei roto te otinga tauira ki roto i te ine o te ine NMR. Ka tukuna e te taputapu ngā pāoro auau irirangi hei whakaoho i ngā whakawhiti taumata pūngao karihi i roto i ngā ngota o ngā ngota tauira. He rerekē te mimiti me te tuku o ngā tohu auau irirangi i roto i ngā taiao matū rerekē, ka hua ake he tihi motuhake i roto i te whānuitanga NMR. Mā te tātari i te taiao matū o ia ngota hauwai i roto i te ngota waikawa propionic, me ngā mōhiohio pērā i te tūranga tihi (nekehanga matū) me te wehenga tihi (pūmau hononga), ka taea te whakaū i te hanganga o te waikawa propionic. Ka taea hoki te mahi tātari tauanga o tōna ihirangi ki tētahi taumata. Heoi, ko te ine NMR he iti ake te tika mō te tātari tauanga ki te whakataurite ki ētahi atu tikanga, engari he painga ahurei mō te tātari hanganga.
