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...
Magnetic resonance spectroscopy of single biomolecules under near-physiological conditions could substantially advance understanding of their biological function, but this approach remains very challenging. Here we used nitrogen-vacancy centers in diamonds to detect electron spin resonance spectra of individual,...

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. ...
(X-ray Auger electron spectroscopy), and e.s.r. (electron spin resonance) studies of palladium, zinc, silver and copper(II) 12-molybdophosphates (3–) in the solid state have been made with reference to the behaviour of electrons formed by reduction with hydrogen. The results obtained ...

spectroscopy to probe spin within the orbital excited-state. Our experiments determine the excited-state spin Hamiltonian, including a room-temperature zero-field splitting of 2.1 GHz and a g-factor similar to that of the ground-state. We confirm that the resonance is associated with spin ...
Electron spin resonance (ESR) spectroscopy's affinity for detecting paramagnetic free radicals, or spins, has been increasingly employed to examine a large variety of biochemical interactions. Such paramagnetic species are broadly found in nature and can be intrinsic (defects in solid-state materials ...
Although review papers exist pertaining to the use of electron spin resonance (ESR) spectroscopy in polymer science, to detect transient radicals formed during the initiation and propagation steps of polymerization and in polymer degradation 1 and in biochemistry 2...
