This method generates atomwise and bondwise attributions from any dataset of accurate values of a chemical property of interest for chemically valid molecules. The explanation e for the selected chemical property p for atom or bond i is here defined as the signed difference in chemical properties between the molecule M and paired molecule M', shown in Eq. 1 and Figures . The paired molecule M' is defined in Eq. 2 by applying the chemical operator 𝑜 on atom or bond i in molecule M.
