位移參數(shù)修改
|
|
|
最近投了一篇文章到 J.Mol.Struct.,審稿人說Na的位移參數(shù)有問題,需要修改. 審稿意見如下: Reviewer #1: This well written paper lacks in a detailed analysis of the displacement parameters in the structure. The sodium atom apeears isotropically refined, with an enormously large value; considering it to be the heaviest atom in the structure, this is unusual. My suspicion is that the sodium atom may be disordered, my suspicion supported by larger thermal parameters of the oxygen close by and a rather large R1 value. Thus, the authors need to 1) resolve the Na-displacement parameter problem, 2) submit a cif-file, 3) provide a checkcif output, without which the paper cannot be accepted. Although these improvements will not make any change to the argumentation in the manuscript, it will enhance the quality of the presented data considerably. 哪位高手幫忙解答下這個問題, 修改一下cif, 謝謝! |
