电子自旋共振是 Electron Spin Resonance的译文,缩写为ESR。ESR技术指的是电子自旋共振波谱技术,可以直接鉴定生化、辐照、解聚、聚合、光化和催化等过程中产生的自由基,判别自由基的种类,且可追踪过程的始终;它还可研究过渡金属离子的能级结构等。ESR技术已非常广泛地用于研究非偶电子的分子,对于偶数电子结构的分子可采用自旋标记技术加以研究。这一技 Electron Spin Resonance is a translation of Electron Spin Resonance, abbreviated as ESR. ESR technology refers to the electron spin resonance spectroscopy technology. It can directly identify free radicals generated in the processes of biochemistry, irradiation, depolymerization, polymerization, photochemistry and catalysis, and classify free radicals, and can always trace the process; It can also study the energy level structure of transition metal ions. ESR technology has been widely used to study non-even-electron molecules, molecules for even-numbered electronic structures can be studied using spin-labeling techniques. This technique
