Erekitironi rudzi rwekutanga kwechero iine imwe hombe uye yakaipa mhosva. Inogona kuita mhando mbiri dzekufamba; imwe ndeyekufamba pamharadzano yakatenderedza nucleus, uye imwe yacho kutenderera pane axis ichipfuura nepakati payo. Sezvo kufamba kwemaerekitironi kuchigadzira nguva, mafungu uye nguva dzemagineti zvinogadzirwa panguva yekufamba. Mune iyo inogara yakaitwa magnetic field H, iyo magnetic nguva yeelectron inoita sediki diki remagineti tsono kana tsono. Sezvo spin huwandu hwehuwandu hweiyo elektroni iri 1/2, iyo elekitironi ine maviri chete maitiro kune iyo yekunze magineti munda: imwe yakafanana neH, inoenderana yakaderera simba Chikamu, simba iri -1 / 2gβH; imwe inopesana neH, inowirirana neyakakwira simba, simba iri + 1 / 2gβH, uye musiyano wesimba pakati pematanho maviri aya gβH. Kana iri munzira yakanangana naH, magetsi emagetsi e frequency v akawedzerwa kusangana nemamiriro e hv = gβH, maelectroniki epasi-simba anotora magetsi emagetsi emagetsi uye osvetukira padanho repamusoro resimba, iro rinodaidzwa kuti paramagnetic resonance yemagetsi. .

Zvinhu zvine mahara maerekitironi (kana maerekitironi ega) anoonekwa mune molekyumu orbital. Senge mahara radicals (mamorekuru ane elektroni imwe chete), dibasic uye polybasic (mamorekuru ane maerekitironi maviri kana anopfuura), matatu mamorekuru (zvakare ane maelectrononi maviri asina kuroorwa mune mamorekuru orbital, asi iwo ari kure kure kwazvo Munguva pfupi yapfuura, kune yakasimba kudyidzana kwemagineti pakati peumwe neumwe, izvo zvakasiyana nedhiviri base) zvichingodaro.

Zvinhu zvine maelectrononi chete anoonekwa mumaatomic orbitals, senge maalikali esimbi maatomu, shanduko yesimbi ion (inosanganisira iron group, palladium boka, uye platinamu boka ions, iro rakazadza 3d, 4d, 5d makomba), isingawanzo pasi epasi simbi ion (Na underfilled 4f shell) zvichingodaro.
