Rdkit reaction smiles
WebIn the SMILES language, there are two fundamental types of symbols: atoms and bonds. Using these SMILES symbols, once can specify a molecule's graph (its "nodes" and "edges") and assign "labels" to the components of the graph (that is, say what type of atom each node represents, and what type of bond each edge represents). WebJun 6, 2024 · Add a comment. 2. SMILES also exist in kekulized and non-kekulized forms. The kekulized form makes the double bonds in aromatic rings explicit. Instead, the normal (canonical) SMILES omits the double bond symbol = in favor of lowercase characters to denote aromaticity. For example: Canonical SMILES: CC (C) (C)c1cc (O)ccc1O. Kekulized:
