I-LADP-1A Uhlelo Lokuhlola lwe-CW NMR – Imodeli Ethuthukisiwe
Incazelo
Ingxenye ozikhethela yona:Imitha yefrequency, ingxenye elungiselelwe wena oscilloscope
Lolu hlelo lokuhlola lwe-continuous-wave nuclear magnetic resonance (CW-NMR) luqukethe uzibuthe ophezulu we-homogeneity kanye neyunithi yomshini oyinhloko.Umazibuthe unomphela usetshenziselwa ukunikeza inkambu kazibuthe eyinhloko ebekwe ngaphezu kwenkundla kazibuthe eguquguqukayo, ekhiqizwe ipheya lamakhoyili, ukuvumela ukulungiswa okuhle kwengqikithi yakazibuthe kanye nokunxephezela ukushintshashintsha kwezinto ezibangelwa ukuhlukahluka kwezinga lokushisa.
Ngenxa yokuthi i-magnetizing yamanje encane kuphela edingekayo endaweni ephansi ye-electromagnetic, inkinga yokushisa yohlelo iyancishiswa.Ngakho, uhlelo lungasetshenziswa ngokuqhubekayo amahora ambalwa.Kuyithuluzi lokuhlola elifanelekile lamalabhorethri efiziksi athuthukile.
Isivivinyo
1. Ukubona isenzakalo senuclear magnetic resonance (NMR) ye-hydrogen nuclei emanzini futhi uqhathanise ithonya lama-ion paramagnetic;
2. Ukulinganisa amapharamitha we-hydrogen nuclei ne-fluorine nuclei, njenge-spin magnetic ratio, i-Lande g factor, njll.
