EPR-72
I-electron luhlobo lwamasuntswana asisiseko anobunzima obuthile kunye nentlawulo embi. Inokwenza iindidi ezimbini zentshukumo; enye kukuhamba kwi-orbit ejikeleze i-nucleus, kwaye enye ijikeleze i-axis edlula embindini wayo. Ekubeni ukuhamba kwee-electron kuvelisa amaxesha, imisinga kunye namaxesha amagnetic aveliswa ngexesha lokuhamba. Kwindawo engaguqukiyo yamagnetic esetyenziswayo H, umzuzu wamagnetic we-electron usebenza njengentonga encinci yamagnetic okanye inaliti. Ekubeni inani le-spin quantum ye-electron yi-1/2, i-electron inezikhokelo ezimbini kuphela kwintsimi yamagnetic yangaphandle: enye ihambelana ne-H, ehambelana neNqanaba lamandla aphantsi, amandla -1 / 2gβH; enye i-antiparallel ukuya ku-H, ehambelana nezinga eliphezulu lamandla, amandla yi-+1/2gβH, kwaye umahluko wamandla phakathi kwamanqanaba amabini yi-gβH. Ukuba kwicala elithe ngqo ku-H, i-electromagnetic wave of frequency v yongezwa ukuhlangabezana nemeko ye-hv=gβH, ii-electron zomgangatho ophantsi wamandla zifunxa i-electromagnetic wave energy kwaye zitsibele kwinqanaba eliphezulu lamandla, elibizwa ngokuba yi-electronic paramagnetic resonance. .
① Izinto ezinee-electron ezingadityaniswanga (okanye ii-electron enye) zivela kwi-molecular orbital. Njengee-radicals zamahhala (iimolekyuli eziqulethe i-electron enye), i-dibasic kunye ne-polybasic (iimolekyuli eziqulethe ii-electron ezimbini okanye ngaphezulu), iimolekyuli ezintathu (zikwanazo ii-electron ezimbini kwi-orbital ye-molecular, kodwa zikude kakhulu Kutshanje, kukho i-elektroni eyomeleleyo. ukusebenzisana kwamagnetic phakathi komnye nomnye, okwahlukileyo kwisiseko esiphindwe kabini) njalo njalo.
② Izinto ezineelektroni ezilodwa ezibonakala kwii-athom ze-athom, ezinjengee-athom zetsimbi yealkali, ii-ion zetsimbi zenguqu (kubandakanywa neqela lentsimbi, iqela le-palladium, kunye ne-ion yeqela leplatinam, ethe yona yazalisa ngaphantsi kwe-3d, 4d, i-5d iigobolondo), ii-ion zetsimbi zomhlaba ezinqabileyo (Nganye iqokobhe elingagcwaliswanga 4f) njalo njalo.
