ELECTRON PARAMAGNETIC RESONANCE IMAGING OF ELECTROCHEMICALLY GENERATED p-PHENYLENEDIAMIANE RADICALS

Electron Paramagnetic Resonance Study of Thermally Generated Radicals in Native and Modified Starches

Quantitative detection of plasma-generated free radicals in liquids by electron paramagnetic resonance spectroscopy

This work focused on qualitative and quantitative detection of oxygen free radicals in liquids after plasma treatment with an atmospheric pressure argon plasma jet by electron paramagnetic resonance spectroscopy (EPR). For the treatment, a shielded plasma jet, where the active effluent zone is surrounded by a protective gas curtain was used.

Semiquinone Radicals from Oxygenated Polychlorinated Biphenyls: Electron Paramagnetic Resonance Studies

Polychlorinated biphenyls (PCBs) can be oxygenated to form very reactive hydroquinone and quinone products. A guiding hypothesis in the PCB research community is that some of the detrimental health effects of some PCBs are a consequence of these oxygenated forms undergoing one-electron oxidation or reduction, generating semiquinone radicals (SQ (*-)). These radicals can enter into a futile redo...

Simultaneous molecular imaging based on electron paramagnetic resonance of 14N- and 15N-labelled nitroxyl radicals.

The major advancement outlined in this communication is the simultaneous visualisation of two kinds of nitroxyl radicals using electron paramagnetic resonance (EPR) spectroscopy and imaging.

Electron Paramagnetic Resonance

where E0 is the energy level without any external magnetic field B = B0êz. Again, g denotes the g factor[5]. For induced transitions, the selection rule is ∆ms = ±1. For unpaired electrons, however, this selection rule is observed for all transitions, as S = 12 and, hence, ms ∈ {− 12 , 2}. The previous formulas are based on the assumption that the response of the material on the external magnet...
