晶體checkcif文件沒(méi)有A,B類錯(cuò)誤,但C類錯(cuò)誤Rint值0.17較大,怎么辦? 已有2人參與

本人有一個(gè)有機(jī)配體的晶體結(jié)構(gòu),已經(jīng)解析出結(jié)構(gòu),checkcif沒(méi)有A、B類錯(cuò)誤,當(dāng)時(shí)就認(rèn)為可以發(fā)表。稿件投出很久,現(xiàn)在審稿人回復(fù)郵件如下: 1 please re-refine the structure with standard uncertainties for the lattice constants. 2 please explain why some reflections are much to weak, and why the Rint is as bad as it is. 3 please provide the experimental information on data collection, diffractometer type, scan mode etc. 4 please add a checkcif file, which fits to the submitted cif file. 麻煩高手們幫忙看看這個(gè)是什么情況?怎么回復(fù)比較好呢?多謝多謝! |

checkcif后的c類錯(cuò)誤如下: Alert level C RINTA01_ALERT_3_C The value of Rint is greater than 0.12 Rint given 0.174 STRVA01_ALERT_2_C Chirality of atom sites is inverted?

1,你的晶包參數(shù)沒(méi)有不確定度,需要給出, 2,解釋為什么衍射點(diǎn)弱,Rint值高, 3,給出數(shù)據(jù)收集的信息,探測(cè)器類型 4,給個(gè)check CIF報(bào)告,和最終的CIF一致的報(bào)告 發(fā)自小木蟲Android客戶端 |
