【摘要】 <正>在测试 CW-ESR 波谱时,如对样品施加外部扰动,所测 ESR 波谱就可能会随之发生相应变化,这样就会得到一系列随外部影响而动态变化的一维 ESR 波谱。利用数学相关分析的方法对这些波谱进行处理,就可获得同步和异步的二维电子自旋共振(2D更多还原

【Abstract】 In the present study,two-dimensional electron spin resonance（2D ESR） spectroscopy is used to study the complex reaction of benzo-15-crown-5（B15C5） with Cu²⁺.Synchronous and asynchronous 2D ESR correlation spectra defined by two independent magnetic field variable axes are obtained by a correlation analysis of dynamic fluctuations of ESR signals induced by changing the concentration ration of B15C5 to Cu²⁺.R is found that different Cu（Ⅱ）complexes can be not only distinguished based on the 2D ESR spectra,but weak peaks covered with strong ones can also be detected.更多还原
