LADP-3 Microwave Electron Spin Resonance Apparatus

Lus piav qhia luv luv:

Electron spin resonance tseem hu ua electron paramagnetic resonance, uas yog hais txog qhov tshwm sim ntawm resonance hloov ntawm lub zog sib nqus ntawm cov electron spin magnetic lub sij hawm thaum nws raug cuam tshuam los ntawm cov zaus electromagnetic yoj nyob rau hauv magnetic teb.Qhov tshwm sim no tuaj yeem pom nyob rau hauv cov ntaub ntawv paramagnetic nrog unpaired spin magnetic moments (piv txwv li cov tebchaw uas muaj cov hluav taws xob tsis sib xws).Yog li ntawd, electron spin resonance yog ib txoj hauv kev tseem ceeb los kuaj xyuas cov khoom siv hluav taws xob tsis sib xws hauv cov teeb meem thiab lawv cov kev cuam tshuam nrog cov atoms nyob ib puag ncig, thiaj li tau txais cov ntaub ntawv hais txog microstructure ntawm cov khoom.Cov txheej txheem no muaj qhov rhiab heev thiab kev daws teeb meem, thiab tuaj yeem siv los txheeb xyuas cov khoom kom ntxaws yam tsis muaj kev puas tsuaj rau cov qauv qauv thiab tsis cuam tshuam rau cov tshuaj tiv thaiv.Tam sim no, nws yog dav siv nyob rau hauv kev tshawb fawb ntawm physics, chemistry, biology thiab tshuaj.
