Uhlelo Lokuhlola LADP-1 lwe-CW NMR - Imodeli Ethuthukile

I-Nuclear magnetic resonance (i-NMR) uhlobo lwesimo sokuguquguquka kwesigqi esibangelwa igagasi lamagnetic ku-magnetic field njalo. Kusukela lezi zifundo zenziwa ngo-1946, izindlela namasu we-nuclear magnetic resonance (NMR) athuthukiswe ngokushesha futhi asetshenziswa kabanzi ngoba angangena ajule entweni ngaphandle kokubhubhisa isampula, futhi abe nezinzuzo zokushesha, ukunemba nokuphakama isinqumo. Kulezi zinsuku, sebengene kusuka kwi-physics baya kumakhemikhali, i-biology, i-geology, ukwelashwa, izinto zokwakha neminye imikhakha, bedlala indima enkulu ocwaningweni nakwisayensi.

Ingxenye ongayikhetha: Imitha yemvamisa, i-oscilloscope eyenzelwe wena uqobo

Lolu hlelo lokuhlola lwe-resonance yamagnetic magnetic resonance eqhubekayo (CW-NMR) iqukethe uzibuthe ophakeme wehomogeneity kanye nomshini oyinhloko womshini. Kusetshenziswa uzibuthe waphakade ukunikeza amandla kazibuthe aphambili abekwe phezulu yinkambu kagesi eguquguqukayo, eyenziwe ngamakhoyili amabili, ukuvumela ukuhleleka okuhle kukazibuthe ophelele nokukhokhela ukuguquguquka kwensimu kazibuthe okubangelwa ukwehluka kwamazinga okushisa.

Ngoba kudingeka amandla amancane amagesi amancane kuphela emkhakheni we-electromagnetic ophansi, inkinga yokushisa kohlelo incishisiwe. Ngakho-ke, uhlelo lungaqhutshwa ngokuqhubekayo amahora amaningana. Kuyithuluzi lokuhlola elifanele lamalabhorethri athuthukile we-physics.

Imininingwane

Isilingo

1. Ukubheka isimo se-nuclear magnetic resonance (NMR) se-hydrogen nuclei emanzini bese uqhathanisa ithonya lama-paramagnetic ion;

2. Ukukala imingcele ye-hydrogen nuclei ne-fluorine nuclei, njenge-spin magnetic ratio, i-Lande g factor, njll.
