WebDec 1, 2024 · on Dec 1, 2024 Hi, I am working on intramolecular hydrogen bonds (IMHB). Assuming the conformer is known, I am curious whether we could get the number of IMHBs. By the way, I noticed that the number of hydrogen bond acceptors and donors can be calculated by rdkit.Chem.Lipinski module. Maybe this module is helpful.
