电子自旋共振谱技术(electron spin-resonance spectroscopy,ESR) 证明膜脂流动性的一种方法。在该技术中将一个含有不配对的电子基团(通常是硝基氧基团)加到磷脂的脂肪酸尾端,这就是所谓的自旋标记(spin-label )。当将这种脂暴露于外加磁场时,由于不配对电子基团的存在,它能够自旋产生顺磁场信号,这种共振能够被仪器检...
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。
Electron spin resonance (ESR) spectroscopy has broad applications in physics, chemistry, and biology. As a complementary tool, zero-field ESR (ZF-ESR) spectroscopy has been proposed for decades and shown its own benefits for investigating the electron fine and hyperfine interaction. However, the ZF...

ESR spectra reveal that C1 activated at 100 °C contains Cusites of tetrahedral symmetry with and while at a higher activation temperature of 400 °C Cusites with a different symmetry are produced corresponding to and C2 activated at 100 °C contains almost exclusively Cusites of trigonal ...
the JES-X320 employs a Hall element with good linearity, and the entire Hall element is thermally controlled to guarantee a magnetic field stability as high as 5 x 10-6/0C・h. The high stability shown is 100 times superimposed ESR spectra of perylene cation radical with ±0.1 mT magnetic...
关键词: 电子自旋共振 , electron spin resonance , ESR , 电子顺磁共振 , electron paramagnetic resonance , EPR 在我们日常生活中常使用的许多塑胶材料,其制程中基本皆是自由基聚合反应生产的。假如可以直接观察到这种自由基聚合反应,将可以获得大量有用的讯息应用在制程或是材料的改良上。因此利用ESR来检测,虽然只...
assumed that the restriction on molecular tumbling of the probe which occurred after association with the micelles was responsible for the broadening of the electron spin resonance (ESR) spectra and excluded consideration of the exchange of solubilized spin probe between bulk water and micellar ...
Electron spin resonance (ESR) spectroscopy, invented by Zavoiskii in 1944, is similar to NMR spectroscopy. ESR spectroscopy is an absorption spectroscopy which involves the absorption of radiation in the microwave region (10 4 –10 6 MHz) by substances containing one or more unpaired electrons. ...
