的意思 diastereomer

1. The two molecules are diastereomers because they have the same molecular formula but different spatial arrangements of atoms.
这两个分子是不对映体异构体，因为它们具有相同的分子式，但原子的空间排列不同。

2. In order to separate the diastereomers, we will need to use chromatography techniques.
为了分离这些不对映体异构体，我们需要使用色谱技术。

3. Diastereomers have different physical properties, such as boiling points and solubilities.
不对映体异构体有不同的物理性质，比如沸点和溶解性。

4. The two compounds are diastereomers, as they are non-superimposable mirror images of each other.
这两种化合物是不对映体异构体，因为它们是彼此的非可重叠镜像。

5. By carefully analyzing the NMR spectrum, we were able to determine that the compound exists as a mixture of diastereomers.
通过仔细分析核磁共振谱，我们能够确定这种化合物存在不对映异构体的混合物。

6. The formation of diastereomers in this reaction is due to the presence of a chiral center in the starting material.
在这个反应中形成不对映体异构体是由于起始物中存在手性中心。
