LADP-3 Microwave Electron Spin Resonance Lisebelisoa
Electron spin resonance e boetse e bitsoa resonance ea elektrone ea paramagnetic, e bolelang ketsahalo ea phetoho ea molumo lipakeng tsa matla a khoheli a elektronike ea motlakase ha e angoa ke leqhubu le tsamaellanang le maqhubu a motlakase khoheli. Ketsahalo ena e ka bonoa ka thepa ea paramagnetic e nang le nako e sa sebetsaneng ea matla a khoheli (ke hore, metsoako e nang le lielektrone tse sa kopaneng). Ka hona, elektrone spin resonance ke mokhoa oa bohlokoa oa ho bona lielektrone tse sa koaheloang ka taba le ts'ebelisano ea tsona le liathomo tse haufi, e le ho fumana leseli mabapi le microstructure ea sesebelisoa. Mokhoa ona o na le kutloisiso e phahameng le tharollo, 'me o ka sebelisoa ho sekaseka litaba ka botlalo ntle le ho senya sebopeho sa mohlala mme ho se na tšitiso ea karabelo ea lik'hemik'hale. Hona joale, e sebelisoa haholo lipatlisisong tsa fisiks, chemistry, biology le bongaka.
Liteko
1. Ithute 'me u ananele ketsahalo ea molumo oa elektronike.
2. Lekanya Lande's g-ntlha ea sampole ea DPPH.
3. Ithute ho sebelisa lisebelisoa tsa microwave tsamaisong ea EPR.
4. Utloisisa leqhubu le emeng ka ho fetola bolelele ba molumo oa maqhubu le ho bona hore na boka ba bokae ba wave.
5. Lekanya kabo ea tšimo ea leqhubu le emeng ka har'a lehare le etsang qeto.
