I-LADP-3 Microwave Electron Spin Resonance Apparatus

Incazelo emfushane:

I-Electron spin resonance ibizwa nangokuthi i-electron paramagnetic resonance, ebhekisela esimweni sokushintshwa kwe-resonance phakathi kwamazinga kazibuthe wamandla kazibuthe we-electron spin umzuzu kazibuthe lapho ethintwa igagasi le-electromagnetic elihambisanayo endaweni kazibuthe.Lesi simo singabonwa ezintweni ze-paramagnetic ezinezikhathi kazibuthe ezijikelezayo (okungukuthi izinhlanganisela eziqukethe ama-electron angahlanganisiwe).Ngakho-ke, i-electron spin resonance iyindlela ebalulekile yokuthola ama-electron angahlanganisiwe endabeni kanye nokusebenzisana kwawo nama-athomu azungezile, ukuze uthole ulwazi mayelana ne-microstructure yezinto.Le ndlela inokuzwela okukhulu nokulungiswa, futhi ingasetshenziswa ukuhlaziya izinto ngokuningiliziwe ngaphandle kokulimaza isakhiwo sesampula futhi akukho ukuphazamiseka kokusabela kwamakhemikhali.Njengamanje, isetshenziswa kabanzi ocwaningweni lwe-physics, chemistry, biology kanye nemithi.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Izivivinyo

1. Tadisha futhi uvume ukuthi i-electron spin resonance phenomenon.

2. Kala ekaLandeg-isici sesampula ye-DPPH.

3. Funda indlela yokusebenzisa amadivaysi e-microwave ohlelweni lwe-EPR.

4. Qonda igagasi elimile ngokushintsha ubude bomgodi ozwakalayo futhi unqume ubude begagasi be-waveguide.

5. Linganisa ukusabalalisa kwenkundla yegagasi elimile endaweni enomsindo futhi unqume ubude begagasi begagasi.
