1·All the physical properties should be identical except for the optical rotations of the two isomers (enantiomers), which are of opposite sign.
这两个异构体(对映体)除了旋光度有相反的符号之外,其他所有的物理性质都应该是完全相同的。
2·First, amylose was selected as chiral selector and the enantiomeric separation of citalopram enantiomers was achieved successfully.
首先以可溶性淀粉这种多糖作为手性选择剂,成功实现了西酞普兰对映体的手性分离。
