What Is Stereochemistry

This section provides a quick introduction on stereochemistry, which is the study of stereoisomers, which are molecules having same atoms and same connectivities, but with different spatial arrangements.

What Is Stereochemistry? - Stereochemistry is the study of stereoisomers, which are molecules having same atoms and same connectivities, but with different spatial arrangements.

Here are some stereoisomers listed in the picture below:

You can do stereochemistry with Open Babel. But you need to understand how stereoinformation (information for stereochemistry) is managed in Open Babel.

The next tutorials will show you some features, limitations and issues with stereoinformation in Open Babel. More more information, see the official documentation of "Open Babel 3.0.1 documentation - Stereochemistry" at https://open-babel.readthedocs.io/en/latest/Stereochemistry/stereo.html.
