WebSince, we did not explicitly designate a bond between the two atoms RDKit assumed we dont care if the bond is a single bond ( -) OR (,) an aromatic bond (: ), hence the characters between our atoms. Bond types can also be searched with characters for single ( - ), double ( = ), triple ( # ), aromatic (: ), ring bond ( @ ), or any ( ~ ). WebAug 16, 2024 · RDKit is a collection of cheminformatics and machine-learning software written in C++ and Python. In this tutorial, RDKit is used to conveniently and efficiently transform SMILES to molecule objects, and then from those obtain sets of atoms and bonds. SMILES expresses the structure of a given molecule in the form of an ASCII string.
