电子自旋共振(electron spin resonance,ESR),又称电子顺磁共振(electron paramagnetic resonance,EPR)。 分子中的电子大多都是成对的,根据泡利不相容原理(Pauli exclusion principle)或包立不兼容原理 ,每个电子对中的电子必为一个自旋向上,一个自旋向下,所以磁性互相抵消。 因此粒子有不成对电子时能表现磁共振的现象。

Application of Electron Spin Resonance (ESR) Spectroscopy in Soil Chemistry Organic free radicals and most transition metal ions are characterized by the presence in their structure of one or more unpaired electron(s), that is, the... N Senesi - Springer New York 被引量: 113发表: 1990年 Cha...
Electron spin resonance spin-trapping detection of radical intermediates in N-doped TiO2-assisted photodegradation of 4-chlorophenol. The electron spin resonance (ESR) spin-trapping technique using 5,5-dimethyl-1-pyrroline-N-oxide as the spin-trap reagent has been applied to detect free r... H ...
摘要: We report electron spin resonance experiments of Gd~(3+) in the Gd_mM_nIn_(3m+2n) (M=Rh,Ir; n=0,l; m=1,2) intermetallic compounds. For T>T_N～45 K, all compounds present a single Dysonian resonance and show a Korringa-like temperature dependence of the lin...
Electron spin resonance of bis(1-phenylborabenzene)cobalt(II) Electron spin resonance measurements of bis(1-phenylborabenzene)cobalt(II) in toluene–ether solution at 77 K yields the following parameters: gx= 2·130, ... GE Herberich,T Lund,JB Raynor - 《Journal of the Chemical Society Dal...
Electron spin resonance (ESR) spectra of surface and interface recombination centers recently observed on (001) silicon wafers, labeled Pand KU1, were studied using spin dependent microwave photoconductivity. Both ESR spectra, having the orthorhombic symmetry and spins S = 1/2 and S = 1 for Pand...
The electron spin resonance (ESR) spin-trapping technique using 5,5-dimethyl-1-pyrroline-N-oxide as the spin-trap reagent has been applied to detect free radical intermediates generated during in situ ultraviolet or visible irradiation of aqueous 4-chlorphenol (4-CP)/N-doped TiO(2) suspensions...
