Faahfaahinta alaabta

Calaamadaha alaabta

Qaylo-dhaan elektaroonig ah ayaa sidoo kale loo yaqaan 'electron paramagnetic resonance', oo loola jeedo ifafaalaha u-gudubka isbeddelka u dhexeeya heerarka tamarta birlabta ee xilligan magnet-ka ee 'electron spin' daqiiqadda markii uu saameeyo mawjadda elektromagnetic ee inta u dhiganta ee aagga magnetka. Dhacdadan waxaa lagu arki karaa walxaha xagjirka ah ee leh daqiiqado magnetic wareega aan kala go 'lahayn (ie xeryahooda ay ku jiraan elektaroonig aan la kala bixin). Sidaa darteed, dhawaaqa wareegga elektaroonigga waa hab muhiim ah oo lagu ogaado elektaroonigyada aan kala go 'lahayn arrinta iyo isdhexgalka ay la leeyihiin atomyada ku xeeran, si loo helo macluumaadka ku saabsan microstructure-ka maaddada. Habkani wuxuu leeyahay xasaasiyad sare iyo xallin, waxaana loo isticmaali karaa in lagu falanqeeyo maaddada si faahfaahsan iyada oo aan la dhaawicin qaab dhismeedka muunadda oo aan faragalin lagu sameyn karin falcelinta kiimikada. Waqtigan xaadirka ah, waxaa si ballaaran loogu adeegsadaa cilmi-baarista fiisikiska, kimistariga, bayoolajiga iyo daawada.

Tijaabooyin

1. Baro oo aqoonso ifafaalaha uumiga elektaroonigga.

2. Cabir Lande's g-qodobka saamiga DPPH.

3. Baro sida loogu isticmaalo qalabka microwave-ka nidaamka EPR.

4. Fahmitaanka mawjadda taagan adoo beddelaya dhererka saqafka u dhawaaqaya oo go'aaminaya dhererka dhererka mawjadaha.

5. Ku cabir qaybinta mawjadda taagan ee daloolka uxanka iyo go'aaminta dhererka dhererka mawjadaha.
