摘要
在数学相关分析的基础上,建立了获得连续波电子自旋共振(continuous-wave electron spin resonance,CW-ESR)的二维相关谱的方法。对光照产生的2-甲基-2-亚硝基-丙烷(2-methyl-2-nitrosopropane,MNP)的白捕捉自由基的一系列CW-ESR谱进行相关分析处理,首次得到了同步和异步的二维电子自旋共振(2D ESR)相关谱。这种利用数学相关分析方法所得到的2D ESR相关谱将为扩大CW-ESR的应用领域及获取更多的有用信息开拓新的途径。
In this paper, the basic theory about two-dimensional electron spin resonance (2D ESR) spectroscopy obtained from continuous-wave ESR (CW-ESR) spectra is described. Synchronous and asynchronous 2D ESR correlation spectra defined by two independent magnetic field variable axes are generated by a correlation analysis of dynamic fluctuations of ESR signals induced by an external perturbation. An example of 2D ESR spectra is presented for a radical produced by self-trapping of 2-methyl-2-nitrosopropane (MNP) under UV irradiation. Potential applications of this new 2D ESR technique are discussed.
