求助B類錯誤一個PLAT035_ALERT_1_B No _chemical_absolute_configuration info
|
求助![]() PLAT035_ALERT_1_B No _chemical_absolute_configuration info given . ?這個錯誤怎么消除 謝謝各位啦~~~~~~~~~~~ ![]() PLAT035 Type_1 Check for _chemical_absolute_configuration的解釋如下,沒看懂 Options are 'rm', 'ad', 'rmad', 'syn', 'unk' or '.' rm : absolute configuration established by the structure determination of a compound containing a chiral reference molecule of known absolute configuration. ad : absolute configuration established by anomalous dispersion effects in diffraction measurements on the crystal. rmad : absolute configuration established by the structure determination of a compound containing a chiral reference molecule of known absolute configuration and confirmed by anomalous dispersion effects in diffraction measurements on the crystal. syn : absolute configuration has not been established by anomalous dispersion effects in diffraction measurements on the crystal. The enantiomer has been assigned by reference to an unchanging chiral centre in the synthetic procedure. unk : absolute configuration is unknown, there being no firm chemical evidence for its assignment to hand and it having not been established by anomalous dispersion effects in diffraction measurements on the crystal. An arbitrary choice of enantiomer has been made. . : inapplicable. |

rm: 得到單晶之前已知手性 ad:絕對構(gòu)型通過flack常數(shù)來確定(Mo靶要求結(jié)構(gòu)中有比P重的原子) rmad: 以上兩者兼而有之 syn:絕對構(gòu)型沒有通過反常散射(flack常數(shù))來確定,手性比例跟合成原料相一致,要求原料的手性比例在合成中不發(fā)生變化 unk:無法確定 . :不適用 |
