求高手幫忙解決游離水的加氫和無序的問題！
|
||
|
晶體結構已經(jīng)解析好了，就是其中有一個游離水O10熱因子太大，編輯建議做無序處理。本人不是很懂，處理了一下，結果編輯又說，檢測CIF表明結構解析還需進一步進行，主要問題是結晶水上缺氫且占有率0.83也不合化學理。 請高手出馬幫忙解決一下，不勝感激！ 2043(12.25).rar(1.59MB) http://kuai.xunlei.com/d/LnU4Db-WAhTpUAQA3d1?p=130497 |

PUBL017_ALERT_1_G The _publ_section_references section is missing or empty. 7 ALERT level A = Data missing that is essential or data in wrong format 2 ALERT level G = General alerts. Data that may be required is missing Publication of your CIF You should attempt to resolve as many as possible of the alerts in all categories. Often the minor alerts point to easily fixed oversights, errors and omissions in your CIF or refinement strategy, so attention to these fine details can be worthwhile. In order to resolve some of the more serious problems it may be necessary to carry out additional measurements or structure refinements. However, the nature of your study may justify the reported deviations from journal submission requirements and the more serious of these should be commented upon in the discussion or experimental section of a paper or in the "special_details" fields of the CIF. checkCIF was carefully designed to identify outliers and unusual parameters, but every test has its limitations and alerts that are not important in a particular case may appear. Conversely, the absence of alerts does not guarantee there are no aspects of the results needing attention. It is up to the individual to critically assess their own results and, if necessary, seek expert advice. If level A alerts remain, which you believe to be justified deviations, and you intend to submit this CIF for publication in Acta Crystallographica Section C or Section E, you should additionally insert an explanation in your CIF using the Validation Reply Form (VRF) below. Your explanation will be considered as part of the review process. If you intend to submit to another section of Acta Crystallographica or Journal of Applied Crystallography or Journal of Synchrotron Radiation, you should make sure that at least a basic structural check is run on the final version of your CIF prior to submission. # start Validation Reply Form _vrf_PUBL004_GLOBAL ; PROBLEM: The contact author’s name and address are missing, RESPONSE: ... ; _vrf_PUBL005_GLOBAL ; PROBLEM: _publ_contact_author_email, _publ_contact_author_fax and RESPONSE: ... ; _vrf_PUBL006_GLOBAL ; PROBLEM: _publ_requested_journal is missing RESPONSE: ... ; _vrf_PUBL008_GLOBAL ; PROBLEM: _publ_section_title is missing.

RESPONSE: ... ; # end Validation Reply Form If you wish to submit your CIF for publication in Acta Crystallographica Section C or E, you should upload your CIF via the web. If your CIF is to form part of a submission to another IUCr journal, you will be asked, either during electronic submission or by the Co-editor handling your paper, to upload your CIF via our web site.
