EPR-72
Erekitironi imhando yechinhu chekutanga chine huremu uye chaji isina kunaka. Inogona kuita marudzi maviri ekufamba; imwe ndeyekufamba pane orbit yakatenderedza nucleus, uye imwe ndeyekutenderera paaxis inopfuura nepakati payo. Sezvo kufamba kwema electrons kuchigadzira nguva, mafungu uye magineti nguva inogadzirwa panguva yekufamba. Munzvimbo inogaro shandiswa yemagineti H, nguva yemagineti yeerekitironi inoita sediki remagineti tsvimbo kana tsono. Sezvo iyo spin quantum nhamba ye electron iri 1/2, erekitironi ine maitiro maviri chete mune yekunze magnetic field: imwe inofananidzwa neH, inoenderana nechepasi simba Level, simba -1 / 2gβH; imwe inopesana neH, inoenderana nehuwandu hwesimba, simba iri + 1/2gβH, uye mutsauko wesimba pakati pemazinga maviri gβH. Kana munzira yakatarisana neH, iyo electromagnetic wave yefrequency v inowedzerwa kusangana nemamiriro ehv=gβH, maerekitironi akadzika-energy level anotora simba remagetsi emagetsi uye anosvetukira padanho repamusoro resimba, iro rinonzi electronic paramagnetic resonance. .
①Zvinhu zvine maerekitironi asina kupetwa (kana maerekitironi ega) zvinoonekwa mumolecular orbital. Zvakadai semahara radicals (mamorekuru ane erekitironi imwe chete), dibasic uye polybasic (mamorekuru ane maviri kana anopfuura maerekitironi ega ega), mamorekuru matatu (anewo maerekitironi maviri ari muchikamu che orbital, asi ari kure kwazvo Munguva pfupi yapfuura, kune simba rakasimba. kupindirana kwemagineti pakati peumwe neumwe, izvo zvakasiyana kubva kune kaviri base) zvichingodaro.
②Zvinhu zvine maerekitironi ega anoonekwa mumaatomu orbitals, senge alkali simbi maatomu, transition simbi ions (kusanganisira iron boka, palladium boka, uye platinum boka ions, iyo yakazove yazara pasi 3d, 4d, 5d shells), isingawanzo simbi simbi ions (Ne underfilled 4f shell) zvichingodaro.
1, Magnetic munda siyana: 0 ~ 18000 Gauss inoramba ichichinjika
2, Pole musoro spacing: 72mm
3, Kutonhora nzira: mvura kutonhora
4, Kurema kwese: <2000kg
Inogona kugadzirwa maererano nezvinodiwa nevatengi
