LADP-3 Microwave Electron Spin Resonance Apparatus

Tlhaloso e Khutšoanyane:

Electron spin resonance e boetse e bitsoa electron paramagnetic resonance, e bolelang ketsahalo ea phetoho ea resonance pakeng tsa maemo a matla a khoheli a nako ea makenete ea elektrone ha e angoa ke maqhubu a tšoanang a maqhubu a motlakase sebakeng sa khoheli.Ketsahalo ena e ka bonoa ka lisebelisoa tsa paramagnetic tse nang le linako tse sa sebetseng tsa makenete (ke hore, metsoako e nang le lielektrone tse sa kopaneng).Ka hona, electron spin resonance ke mokhoa oa bohlokoa oa ho lemoha li-electrone tse sa kopanngoeng tabeng le ho sebelisana ha tsona le liathomo tse potolohileng, e le ho fumana boitsebiso bo mabapi le microstructure ea thepa.Mokhoa ona o na le kutlo e phahameng le tharollo, 'me o ka sebelisoa ho sekaseka thepa ka botlalo ntle le ho senya sebopeho sa sampole mme ha ho na tšitiso ea karabelo ea lik'hemik'hale.Hajoale, e sebelisoa haholo lipatlisisong tsa fisiks, k'hemistri, baeloji le bongaka.

Liteko

1. Ho ithuta le ho ananela electron spin resonance phenomenon.

2. Lekanya Lande'sg-mohlala oa DPPH.

3. Ithute ho sebelisa lisebelisoa tsa microwave tsamaisong ea EPR.

4. Utloisisa leqhubu le emeng ka ho fetola bolelele ba cavity ea resonant le ho lekanyetsa bolelele ba waveguide.

5. Lekanya kabo ea tšimo ea maqhubu a emeng sebakeng sa resonant 'me u bone bolelele ba waveguide.
