单词 | stereochemistry |
释义 | stereochemistryn. That department of chemistry which deals with theoretical differences in the relative position in space of atoms in a molecule, in relation to differences in the optical and chemical properties of the substances. Also, the stereochemical properties of something; a stereochemical configuration or arrangement.
