LADP-3 Microwave Electron Spin Resonance Apparatus
Electron spin resonance imatchedwanso electron paramagnetic resonance, yomwe imanena za kusintha kwamphamvu pakati pa maginito amagetsi a electron spin maginito pomwe amakhudzidwa ndimayendedwe ofanana amagetsi amagetsi. Chodabwitsachi chitha kuwonedwa pazida zamagetsi zopanda magwiridwe antchito (mwachitsanzo, mankhwala okhala ndi ma elekitironi osaphatikizika). Chifukwa chake, electron spin resonance ndi njira yofunikira yozindikira ma elekitironi osagundidwa pankhaniyi komanso kulumikizana kwawo ndi maatomu oyandikana nawo, kuti adziwe zambiri zazinthu zazing'ono zomwe zimapangidwazo. Njirayi ili ndi chidwi chachikulu komanso imawongolera, ndipo itha kugwiritsidwa ntchito kupenda zinthuzo mwatsatanetsatane popanda kuwononga kapangidwe kazitsanzo komanso kusasokonezedwa ndimomwe zimachitikira. Pakadali pano, imagwiritsidwa ntchito kwambiri pakufufuza za physics, chemistry, biology ndi mankhwala.
Zoyesera
1. Phunzirani ndikuvomereza chodabwitsa cha ma elekitironi.
2. Measure Lande's g-Choyimira cha DPPH.
3. Phunzirani momwe mungagwiritsire ntchito zida zama microwave mu dongosolo la EPR.
4. Mvetsetsani mafunde oyimirira posintha kutalika kwa mphindikati ndikuzindikira kutalika kwa funde.
5. Muyese magawidwe oyimilira oyimilira m'miyala yolumikizana ndikuzindikira kutalika kwa funde.
