晶体数据审稿意见-测试描述要和CIF中信息一致 审稿意见: Finally, the authors need to properly report how the diffractionexperiments were done. The experimental section of the paper says that the datawas collected using graphite-monochromated Cu radiation, However, the CIFindicates that three structures (la,le, and 3) were collected using Mo radiation, The CIF also says that 2a, 2b, 2c, 2d, and 3 were run on a diffractometer using a mirror monochromator, not agraphite monochromator (the monochromator information was not reported in theCIF for 1a or 1e). 大意: 最后,作者需要正确报告衍射实验是如何完成的。论文的实验部分说,数据是使用石墨单色铜辐射收集的。然而,CIF表明,使用钼辐射收集了三种结构(la、le和3)。CIF还说,2a、2b、2c、2d和3是在使用镜面单色器而不是石墨单色器的衍射仪上运行的(1a或1e的CIF中没有报告单色器信息)。 CIF中记录辐射光源信息的条目为“_diffrn_radiation_type”,记录单色器信息的条目为“_diffrn_radiation_monochromator”(参阅推文“CIF核磁词典-DIFFRN_RADIATION”),以Olex2[2]内置数据sucrose为例,其辐射光源为钼靶(MoKα),单色器为石墨(graphite),如图1所示。 ▲图1 sucrose结构CIF文件部分内容 在撰写实验部分的单晶X射线衍射实验内容时,一定要注意撰写内容和CIF[1]中的信息保持一致,否则就有可能会出现上述类似审稿意见。 视频讲解请参阅: 晶体数据审稿意见-测试描述要和CIF中信息一致:https://www.bilibili.com/video/BV1xF2XY2ErP 参考文献 [1] (a)Hall, S.
