Lub tshuab hluav taws xob tig rov qab lub zog tseem hu ua electron paramagnetic resonance, uas hais txog qhov tshwm sim ntawm kev hloov pauv ntawm qhov sib txawv ntawm lub zog sib nqus ntawm cov hluav taws xob tig sib nqus lub zog thaum nws muaj kev cuam tshuam los ntawm qhov sib xws zaus electromagnetic yoj hauv cov sib nqus. Qhov tshwm sim no tuaj yeem pom nyob hauv cov khoom siv paramagnetic nrog cov kiv kiv tsis muaj zog (piv txwv li cov xaim hluav taws xob uas tsis muaj qhov hluav taws xob). Yog li no, cov cuab yeej hluav taws xob tig rov qab yog ib txoj hauv kev tseem ceeb los nrhiav cov xaim hluav taws xob hauv qhov teeb meem thiab lawv qhov cuam tshuam nrog lwm tus atoms, kom tau txais cov ntaub ntawv hais txog microstructure ntawm cov khoom. Txoj kev no muaj qhov kub siab thiab kev daws teeb meem, thiab tuaj yeem siv los tshuaj xyuas cov ntaub ntawv txhua yam tsis muaj kev cuam tshuam cov qauv qauv thiab tsis muaj kev cuam tshuam rau kev fab tshuaj. Tam sim no, nws yog dav siv hauv kev tshawb fawb ntawm physics, chemistry, biology thiab tshuaj.

Kev sim

1. Kawm thiab paub txog electron spin resonance phenomenon.

2. Ntsuas Lande's g-qhov tseem ceeb ntawm DPPH coj.

3. Kawm siv microwave li hauv EPR system.

4. Nkag siab kev sawv nthwv dej los ntawm kev hloov qhov ntev ntawm cov kab noj hniav ntev thiab txiav txim siab waveguide wavelength.

5. Ntsuas taw nthwv dej ntu xa rau qhov chaw muaj cov kab thiab ua kom pom tseeb ntwm yoj yoj.
