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. WebA bond dissociation reaction can be categorized into one of two types: homolysis where one of the shared pair of electrons in the reactant stays with each product, and heterolysis where both electrons remain with one product, resulting in charged species. ‡ The reactant can also be charged; for example,
