求好心人幫忙精修NH2
|
|
|
本人非晶體專業(yè),請(qǐng)好心人幫忙精修一下NH2,編輯的要求如下: If it is allowed by the quality of the experiment, please refine the amino hydrogens without geometric restrictions. For such prototropic tautomeric systems, the objective positions of the hydrogens are of importance。 后來(lái)有個(gè)本版的好心人幫精修了一下,但好像沒有按編輯的要求精修NH2, 因此編輯的答復(fù)如下: I did not understand what you have done with amino hydrogens. Apparently, you did not refine then, neither their N-H bond lengths were taken standard. Please explain your procedure of treating these hydrogens in details. (這位好心的朋友讓我這么答復(fù):I didn't refine the structure, only using 'afix 3' to ride H atoms on N atom. The distance of N-H was not limited to standard length. (可是編輯要求重新上傳fcf文件,看來(lái)還得精修N上的H) 求別的好心人幫忙按編輯的要求做一下,本人是菜鳥。如果幫忙了,一定感激不盡。ìF(xiàn)金感謝都行,呵呵) 如果愿意幫忙請(qǐng)留下您的郵箱 菜鳥 |
