Superoxide Reaction with Nitroxides
Free Radical Research Communications, 1990Stable, free radical nitroxides are commonly used ESR spectroscopy tools. However, it has recently been found that ESR observable signal from 5-membered ring spin-adducts or stable label nitroxides is lost or diminished by reaction with superoxide. A similar radical-radical annihilation was not found for six membered ring nitroxide radicals. To discern
