In order to make the spin trapping technique more useful in biological free radical studies, using an specially designed ESR cell for in situ electrochemical reactions, five 5-membered ring nitrones, which are analogues of 5,5-dimethyl-1-pyrroline N-oxide (DMPO), one of the most conventionally used spin traps, have been explored for their hydrogen atom (•H) adducts formation. ESR spectra consisting
为了使自旋捕获技术在生物自由基研究中更有用,使用专门设计的 ESR 电池进行原位电化学反应,五个 5 元环硝酮,它们是 5,5-二甲基-1-吡咯啉 N-的类似物氧化物 (DMPO) 是最常用的自旋陷阱之一,已对其氢原子 (•H) 加合物的形成进行了探索。讨论了仅由 •H 加合物组成的 ESR 谱和由此产生的 ESR 参数。
