I-LADP-3 yeMicrowave Electron Spin Resonance Apparatus

Inkcazelo emfutshane:

I-Electron spin resonance ikwabizwa ngokuba yi-electron paramagnetic resonance, ebhekisa kwisenzeko senguqu ye-resonance phakathi kwamanqanaba ombane wemagnethi we-electron spin umzuzu wemagnethi xa ichatshazelwa ngamaza ombane ohambelana nemagnethi kummandla wemagnethi.Lo mcimbi unokubonwa kwizixhobo zeparamagnetic kunye nemizuzu yemagnethi ejikelezayo engadityaniswanga (oko kukuthi iikhompawundi eziqulethe ii-electron ezingadityaniswanga).Ke ngoko, i-electron spin resonance yindlela ebalulekileyo yokufumanisa ii-electron ezingadityaniswanga kwimiba kunye nokusebenzisana kwazo kunye nee-athomu ezijikelezileyo, ukuze ufumane ulwazi malunga ne-microstructure yezinto.Le ndlela inovakalelo oluphezulu kunye nesisombululo, kwaye ingasetyenziselwa ukuhlalutya izinto ngokubanzi ngaphandle kokonakalisa isakhiwo sesampulu kwaye akukho ukuphazamiseka kwi-chemical reaction.Okwangoku, isetyenziswa ngokubanzi kuphando lwefiziksi, ikhemistri, ibhayoloji kunye neyeza.
