I-Electron Paramagnetic Resonance (EPR), ebizwa nangokuthi i-Electron Spin Resonance (ESR) iyindlela ye-magnetic resonance ethola ukuguqulwa kwe-resonance phakathi kwezimo zamandla zama-electron angabhanqiwe endaweni kazibuthe.

Uhlelo lwe-EPR ngokuvamile lwakhiwe uhlelo lukazibuthe, uhlelo lwe-microwave kanye nesistimu yokubona ngogesi. Uhlelo lukazibuthe luvame ukuhlukaniswa ngozibuthe kagesi, omagnethi abangapheli kanye nozibuthe abakhulu ngokwesimiso sokuthi inkambu kazibuthe eyinhloko ikhiqiza insimu kazibuthe. Njengamanje, omazibuthe baphakade kanye nozibuthe kagesi bavame ukusetshenziswa.

Ozibuthe baphakade bangakwazi ukugcina uzibuthe unomphela, izindleko zabo zokwakha nezokugcina ziphansi, futhi bangaklanywa ukuthi bavuleke futhi babe nobubanzi obukhulu, okuyisibusiso ezigulini ezine-claustrophobia.

Umazibuthe ongu-0.041T omkhulukazi wokuvula we-EPR okhiqizwe yi-CSJ uwuzibuthe ongunaphakade. Ozibuthe baphakade basetshenziselwa ukukhiqiza inkambu kazibuthe emile, ikhoyili yokushanela inikezwa amandla okukhiqiza inkambu kazibuthe echemile, futhi ikhoyili yokushintshashintsha inikwa amandla okukhiqiza inkambu kazibuthe eguquliwe. Isebenza nezinye izakhi ukukhiqiza isignali ye-electronic paramagnetic resonance, ngaleyo ndlela ihlanganise isampula yokuhlola. Ukuhlaziywa, isimo, njll.
