I-Electron Paramagnetic Resonance (i-EPR), ekwabizwa ngokuba yi-Electron Spin Resonance (ESR) yindlela yobuchwephesha yemagnethi efumanisa utshintsho lwentetho phakathi kwamandla ombane wee-elektroni ezingafakwanga ndawo kumazibuthe asetyenzisiweyo.

Inkqubo ye-EPR ngokubanzi yenziwe yinkqubo yemagnethi, inkqubo ye-microwave kunye nenkqubo yokufumanisa i-elektroniki. Inkqubo yemagnethi yahlulwe ngokubanzi ngoomazibuthe beemagnethi, iimagnethi ezisisigxina kunye neemagnethi ezihamba phambili ngokubhekisele kumgaqo wokuba eyona nto iphambili kumazibuthe ivelisa amandla kazibuthe. Okwangoku, iimagnethi ezisisigxina kunye nee-electromagnet zihlala zisetyenziswa.

Iimagnethi ezisisigxina zinokugcina umazibuthe ngokusisigxina, iindleko zazo zokwakha kunye nokugcina ziphantsi, kwaye zinokuyilwa ukuba zivuleke kwaye zibe zinkulu ubukhulu, ezilulutho kwizigulana ezine-claustrophobia.

Imagnethi ye-EPR enkulu yokuvula enkulu eveliswe yi-CSJ ngumazibuthe osisigxina. Iimagnethi ezingapheliyo zisetyenziselwa ukuvelisa i-static magnetic field, i-coil coep inikwe amandla okuvelisa i-bias field magnetic, kwaye i-coil modulation inikwe amandla okuvelisa i-magnetic field. Isebenza namanye amacandelo ukwenza i-paramagnetic signal resonance sign, ngaloo ndlela yenza isampulu yovavanyo. Uhlalutyo, ubume, njl.
