投稿過程中編輯就數(shù)據(jù)精修部分提出了下面的幾個問題,不知道如何回答(自己不會解結(jié)構(gòu)),哪位高手可以幫忙,麻煩留下你的電子郵箱我把數(shù)據(jù)給你發(fā)下。 在數(shù)據(jù)精修部分,我是這樣描述的“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). 編輯關(guān)于這一部分的問題如下: 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.
