問(wèn)題1 - Please recheck the positions of H1 and H2. I think that H1 is not well placed. Delete the two from the atom list. Do some cycles of refinements and plave H1 and H2 with help of the difference Fourier map. Then place the protons with: O1 6 0.532025 0.642637 0.206021 11.00000 0.05265 0.02086 = 0.06080 0.00192 0.01990 -0.00491 AFIX 2 H1 2 x y z 11.00000 -1.20000 AFIX 0 O2 6 0.432008 0.292037 0.154513 11.00000 0.05390 0.02536 = 0.05214 -0.01416 0.01485 -0.00338 AFIX 2 H3 2 x y z 11.00000 -1.20000 AFIX 0 where x y z are the positions from the Difference Fourier. For the oxygen atoms use the positions to which the proton is the closest. 問(wèn)題2 - please check these points; maybe you should remove the protons and try to locate them by Fourier difference maps PLAT380_ALERT_4_G Check Incorrectly? Oriented X(sp2)-Methyl Moiety C2 PLAT380_ALERT_4_G Check Incorrectly? Oriented X(sp2)-Methyl Moiety C4 PLAT380_ALERT_4_G Check Incorrectly? Oriented X(sp2)-Methyl Moiety C6 PLAT380_ALERT_4_G Check Incorrectly? Oriented X(sp2)-Methyl Moiety C8 問(wèn)題1和2應(yīng)該是一樣的解決方式吧?從Fourier difference maps中找出H,然后用編輯的方法命名?但如何看Fourier difference maps?怎么從里面找H?命名后還需要refine嗎??求具體的步驟,謝謝啦! 問(wèn)題3 -Insert _iucr_refine_instructions_details (=the last .res-file) in the cif-file. This is not mandatory, but highly recommended 讓我把res復(fù)制進(jìn)來(lái)嗎?在哪段輸入?格式是怎么樣的? 問(wèn)題4 - Give the hall symbol 完全不明白什么意思 真誠(chéng)請(qǐng)求各位高手的幫助! |

謝謝xi老師的回復(fù) 大概是因?yàn)橛袀(gè)這四個(gè)G錯(cuò)誤,編輯讓從新傅里葉加氫,這四個(gè)都是甲基 PLAT380_ALERT_4_G Check Incorrectly? Oriented X(sp2)-Methyl Moiety C2 PLAT380_ALERT_4_G Check Incorrectly? Oriented X(sp2)-Methyl Moiety C4 PLAT380_ALERT_4_G Check Incorrectly? Oriented X(sp2)-Methyl Moiety C6 PLAT380_ALERT_4_G Check Incorrectly? Oriented X(sp2)-Methyl Moiety C8 謝謝指點(diǎn),checkcif看到了 Space group P 21/c Hall group -P 2ybc |
