EPR-60
Electron paramagnetic resonance (EPR) imhando yemagineti resonance tekinoroji yakatanga kubva panguva yemagineti yemaerekitironi asina kupetwa. Inogona kushandiswa kuona nehupamhi uye nehwerengedzo maerekitironi asina kupetwa ari mumaatomu kana mamorekuru ezvinhu, woaongorora. Maitiro ekuumbwa kwenzvimbo yakapoteredza. Kune emahara radicals, iyo orbital magineti nguva inenge isina mhedzisiro, uye yakawanda yenguva yakazara magineti (pamusoro pe99%) inobatsira kune erekitironi spin, saka erekitironi paramagnetic resonance inonziwo "electron spin resonance" (ESR).
Electron paramagnetic resonance yakatanga kuwanikwa neaimbova nyanzvi yefizikisi yeSoviet E·K · Zavois muna 1944 kubva kuMnCl2, CuCl2 nemamwe maparamagnetic munyu. Vefizikisi vakatanga kushandisa nzira iyi kudzidza chimiro chemagetsi, chimiro chekristaro, nguva ye dipole, uye chimiro chemolecular yemamwe maatomu akaomarara. Zvichienderana nemhedzisiro yeerekitironi paramagnetic resonance kuyerwa, machemist akajekesa kemikari zvisungo uye maerekitironi density kugovera mune yakaoma organic komisheni, pamwe nematambudziko mazhinji ane chekuita nemaitiro ekuita. American B. Commoner et al. yakaunza tekinoroji yeelectron paramagnetic resonance kumunda webiology kekutanga muna 1954. Vakaona kuvepo kwemahara radicals mune zvimwe zvirimwa nemhuka. Kubva kuma1960, nekuda kwekuenderera mberi kwekuvandudzwa kwezviridzwa uye kuenderera mberi kwekuvandudza tekinoroji, tekinoroji paramagnetic resonance tekinoroji yakashandiswa mufizikisi, semiconductors, organic chemistry, yakaoma chemistry, radiation chemistry, makemikari engineering, marine chemistry, catalysts, biology, uye. biology. Yakave ichishandiswa zvakanyanya mundima dzakawanda senge chemistry, mushonga, sainzi yezvakatipoteredza, uye geological prospecting.
Inonyanya kushandiswa pakuona kwemahara radicals uye paramagnetic simbi ions uye makomisheni avo kuwana chimiro uye ruzivo rwekuumbwa. Semuyenzaniso: kuyera magineti susceptibility yeparamagnets, kudzidza kwemagineti matete mafirimu, kuitisa maerekitironi musimbi kana semiconductors, kumwe kuremara kwelatisi munzvimbo dzakasimba, kukuvadzwa kwemwaranzi uye kutamiswa kwemwaranzi, ultraviolet radiation inogara kwenguva pfupi organic free radicals Mamiriro emagetsi emagetsi. maitiro ekuita, maitiro emahara radicals mukuora, chimiro chesimbi complexes mukubatanidza chemistry, iyo simba saturation point yebvudzi remunhu mahara radicals, hukama pakati pemahara radicals mumasero tishu nezvirwere, uye maitiro ekusvibisa kwezvakatipoteredza.
1, Magnetic munda siyana: 0 ~ 7000Gauss inoramba ichichinjika
