英语翻译
To systematically evaluate the effect of the nitrophenyl group in 3,we compared the stereoselective coordination of three amino alcohols (8-10) to two Co(III) complexes,(R,R)-1 and (S,S)-3.Although the two cobalt complexes have opposite configurations,
it is evident that the two complexes have the same sense of folding of the diamine backbone.In all of the cases,reversible coordination of the amino alcohols to the cobalt complexes is rapid but slower than the NMR time scale.
Thus,the diastereomeric complexes give distinct H NMR signals.

(首先说明:科技英语,我的原则就是直译,紧挨后面的括号内的解释是您仅供参考的我认为比较合理的推测,另外,为了更清楚的理解,我特意在原文第2句上的汉语译文中标上(a).(b),(c) ,懂英语的人知道这丝毫不会妨碍原意;也有读起来有点别扭的语句,(只有一句),但是,没有任何改变原文的本意:宁信不顺.有些专用术语,有待于专业人员定夺.)
译文:为了系统地评估第3组内硝基苯(物)的影响作用,我们把三种氨基醇(8-10)的立体选择性配位与(a).两种钴(lll)复合物,(b).(R,R),(物),和(c).(S,S)-3,这三类物质(的空间配位)进行对比.虽然这两种钴复合物有相反的立体配位结构,但是,很明显,这两种复合物却有相同的特性,即:二元胺“脊骨”(上的)可折叠性.在以上所有试验中,虽然氨基醇物与钴复合物的可逆式配位(双面配位)是很迅速的,但是,却比NMR (核磁共振)的时标慢的多.因此,不同结构的立体配位复合物会产生完全不同的H NMR (H 核磁共振)信号.
