LADP-3 Microwave Electron Spin Resonance Apparatus

Kufotokozera Kwachidule:

Electron spin resonance imatchedwanso electron paramagnetic resonance, yomwe imatanthawuza zochitika za kusintha kwa resonance pakati pa maginito a mphamvu ya maginito a electron spin maginito mphindi pamene imakhudzidwa ndi mafunde afupipafupi a electromagnetic mu maginito.Chodabwitsa ichi chikhoza kuwonedwa muzinthu za paramagnetic zomwe zimakhala ndi maginito osasinthasintha (ie mankhwala okhala ndi ma elekitironi osalumikizana).Chifukwa chake, ma electron spin resonance ndi njira yofunikira yodziwira ma electron osagwirizana mu nkhani ndi kugwirizana kwawo ndi ma atomu ozungulira, kuti apeze zambiri zokhudza microstructure ya zinthu.Njirayi imakhala ndi mphamvu komanso kusamvana kwakukulu, ndipo ingagwiritsidwe ntchito kusanthula zinthuzo mwatsatanetsatane popanda kuwononga chitsanzo chachitsanzo komanso palibe kusokoneza kwa mankhwala.Pakalipano, amagwiritsidwa ntchito kwambiri pa kafukufuku wa sayansi, chemistry, biology ndi mankhwala.

1. Phunzirani ndi kuvomereza zochitika za electron spin resonance.

2. Yesani za Landeg-Chithunzi cha DPPH.

3. Phunzirani momwe mungagwiritsire ntchito zida za microwave mu dongosolo la EPR.

4. Kumvetsetsa mafunde oima posintha kutalika kwa patsekeke ndikuzindikira kutalika kwa mawonekedwe a waveguide.

5. Yezerani momwe mafundewa amagawidwira m'magawo a resonant ndikuzindikira kutalika kwa mawonekedwe a waveguide.
