关于EPR数据出现的问题
|
 各位大神，，谁比较懂EPR测试中的问题呢？文章审稿意见回来了，提出了几个特别难缠的问题，希望帮我看一下，，这个难题如何解，谢谢呢，，金币金币后续还有哦，1. About EPR spectra. A weak and broad EPR signal (g =2.12) may be attributed to generation of NH radicals and synergetic effect of copper ions, which seems to be incorrect. Firstly, EPR signal for radicals were always around g = 2.00 with small linewidth (about 20 Gauss). Secondly, radicals may be generated in N atoms of pyridine, such as viologen redical (Angew. Chem. Int. Ed. 2007, 46, 3249 –3251). Thirdly, no evidence for appearance of mixed copper valence of 1P was found. Fourthly, whether impurities or vacancy factor lead to unusual EPR signal.  |
