[交流] 【请教】晶体学报E 的编辑给了下面几条修改意见,不知如何解答,请高手指教!

投稿过程中编辑就数据精修部分提出了下面的几个问题,不知道如何回答(自己不会解结构),哪位高手可以帮忙,麻烦留下你的电子邮箱我把数据给你发下。

在数据精修部分,我是这样描述的“All H atoms bounded to C atoms were placed in calculated positions and treated in a riding-model approximation, with C ---H = 0.93 A and Uiso(H)= 1.2 Ueq(O). The positions of carboxylic H atoms were found from a difference Fourier map and refined with distance restraints O---H (carboxyl) = 0.85 A and Uiso(H) = 1.2 Ueq(O). The benzoic acid [C56---C57---C58---C59---C60---C61---C62---O11---O12---H12] was treated as disorder over two sites, with refined ccupancies 0.496(5) and 0.504(5).

编辑关于这一部分的问题如下:
1)There should be much more details about how disorder was treated: why was it introduced; how the occupancies were determined, etc.

2)All non-standard refinement technique and special atom_site_refinement_flags present in the atomic list should be mentioned and justified in publ_section_exptl_refinement.

3)On the other hand, refinement of H atoms with bond restraint should be reflected in the atom_site_refinement_flags in the atomic coordinate table – the atomic coordinate table as it is given below is not consistent
with the above description.

4)_refine_diff_density_max    1.169
_refine_diff_density_min   -1.134
if _refine_diff_density_max and _refine_diff_density_min absolute value is > 1 eA-3, the location of the highest peak and deepest hole should be
given in _publ_section_exptl_refinement.

基本都是修正的时候的描述问题,如果你自己完全不懂的话,建议找帮你修结构的人,问问他该怎么写,这个应该是他比较清楚的。。。。主要是要求你把修正时候的具体细节都要描述下。。。貌似。。
