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 ( ~ ). WebMar 19, 2024 · The model will extract the information of the atoms and bonds which were described as nodes and edges. Node descriptors including atom type, atom degree, atom explicit valence, atom implicit valence, and aromaticity, and edge descriptors including bond type, whether the bond is conjugated, and whether the bond is in-ring a were considered.
