晶體E編輯意見,急求怎么解決
|
|
|
本人新手,對(duì)晶體一竅不通。最近投了一篇晶體E編輯提出錯(cuò)誤如下,請(qǐng)大俠們指教怎么改正。錯(cuò)誤: 1.In the abstract and comments section, could you please provide standard uncertainties for all dihedral angles quoted 2.In '_publ_section_exptl_refinement' you have indicated that the Friedel pairs were merged, This is, in fact, not the case. Friedel pairs were refined in the structure and the absolute configuration determined from this data. Could you please check and correct. 3. In '_publ_section_exptl_refinement' could you provide details of the disorder present in the structure. 4. In '_publ_section_exptl_refinement' could you provide details of the location and refinement of the N-H proton in this compound. 本人是藥物化學(xué)專業(yè)的,對(duì)這個(gè)實(shí)在是搞不明白,希望專業(yè)人士幫幫忙啊。要是需要數(shù)據(jù)我發(fā)到你們郵箱里。謝謝啊! |

1. 給出二面角的標(biāo)準(zhǔn)偏差 一般用xp的mpla吧 2.檢查一下解析時(shí)Friedel pairs應(yīng)該精修了,沒(méi)有merged 3.簡(jiǎn)要描述下無(wú)序的處理 4.N-H的處理,一般是從傅里葉圖中找到然后適當(dāng)限制的吧,具體看自己的結(jié)構(gòu) 不懂的話請(qǐng)教解析的老師吧 |

1.摘要與評(píng)論部分所有二面角增加偏差值(用括號(hào)括起來(lái)); 2.在實(shí)驗(yàn)精修部分,你指出了Friedal對(duì)合并了,但事實(shí)上不是如此,請(qǐng)?jiān)贆z查并改正. 3.請(qǐng)?jiān)趯?shí)驗(yàn)精修部分提供有關(guān)結(jié)構(gòu)中無(wú)序的詳細(xì)信息.即你這個(gè)結(jié)構(gòu)中有無(wú)序,應(yīng)該加以描述. 4.在實(shí)驗(yàn)精修部分請(qǐng)?zhí)峁┯嘘P(guān)N-H質(zhì)子確定與精修的細(xì)節(jié),即你是如何加這個(gè)氫的,如何精修的,例如有否鍵長(zhǎng)限制等. |

CIF中有如下數(shù)據(jù): loop_ _atom_site_label _atom_site_type_symbol _atom_site_fract_x _atom_site_fract_y _atom_site_fract_z _atom_site_U_iso_or_equiv _atom_site_adp_type _atom_site_occupancy _atom_site_symmetry_multiplicity _atom_site_calc_flag _atom_site_refinement_flags _atom_site_disorder_assembly _atom_site_disorder_group 其中: _atom_site_occupancy,就是占有率. |
