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...
Electron spin resonance (esr) (also known as electron paramagnetic resonance, epr) has been successfully applied to biological problems since the late 1950s (Commoner et al ., 1957). The method compares closely with nmr in being essentially nondestructive since the measuring wavelengths fall within...
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。
Among the employed experimental methods the Electron Spin Resonance (ESR) spectroscopy and related ferromagnetic (FM) and antiferromagnetic (AFM) resonance techniques, FMR and AFMR, play an important role in obtaining valuable insights into the static and dynamic magnetic properties of van der Waals co...

The JES-X320 is well designed to meet these requirements. Shown above is an ESR spectrum of Coppinger radical. The smallest split coupling of t-butyl base 4.7 uT, and its split shows a 2.35 uT resolution. High Stability In order to obtain data with excellent reproducibility, a stable and ...
Measurement of the ZF-ESR spectrum of P1 centers.aRevised spin-locking sequence. Instead of sweeping the length of the driving pulse (orange boxes), here we sweep the power of the driving pulse.bEnergy levels of15N P1 centers. Due to the degeneracy of the upper two energy levels, the mag...
Then, we carried out free-induction decay and spin echo measurements of the single NV center to study static and dynamic properties of nanoscale bath spins surrounding the NV center. We also measured ESR spectrum of the bath spins using double electron-electron resonance spectroscopy with the ...
