Imininingwane yomkhiqizo

Amathegi womkhiqizo

I-Electron spin resonance ibizwa nangokuthi i-electron paramagnetic resonance, ebhekisa kokuguqukayo kokuguquguquka kokuphakama kwamandla phakathi kwamazinga kazibuthe wamandla we-electron spin mzuzu lapho kuthinteka imvamisa ehambelana nemvamisa yamagnetic magnetic field kazibuthe. Lo mkhuba ungabonwa ezintweni ze-paramagnetic ezinezikhathi ezingahlobene zesipinikhi (okungukuthi izinhlanganisela eziqukethe ama-electron angahlanganisiwe). Ngakho-ke, i-electron spin resonance iyindlela ebalulekile yokuthola ama-electron angahlanganisiwe endabeni nasekusebenzelaneni kwawo nama-athomu azungezile, ukuze kutholakale imininingwane mayelana nokwakheka kwezinto ezincane kwento. Le ndlela inokuzwela okuphezulu nokuxazululwa, futhi ingasetshenziswa ukuhlaziya imininingwane ngokuningiliziwe ngaphandle kokulimaza ukwakheka kwesampula futhi kungaphazanyiswa nokusabela kwamakhemikhali. Njengamanje, isetshenziswa kabanzi ocwaningweni lwe-physics, chemistry, biology kanye nemithi.

Ukuhlolwa

1. Fundisisa futhi wamukele isimo se-electron spin resonance.

2. Linganisa iLande g-isici sesampula se-DPPH.

3. Funda ukuthi uwasebenzisa kanjani amadivayisi e-microwave ohlelweni lwe-EPR.

4. Qonda ukuma kwamagagasi ngokushintsha ubude bomgogodla futhi unqume ubude begagasi lamaza.

5. Linganisa ukusatshalaliswa kwensimu yama-wave emi emgodini we-resonant bese unquma ubude be-waveguide.
