Two quantities are described: (1) the information content of the like‐spin exchange‐correlation hole, χ XC, and (2) the information content of the Coulomb hole, χ C, of the like‐spin and the unlike‐spin cases. χ XC is capable of describing the electron structure of molecules on the basis of chemical grounds with astonishing accuracy and provides a clear differentiation of the localization degree of electrons, belonging to different molecular basins. Furthermore, χ XC is used as a tool to get insights in the electronic reorganization occurring along a reaction coordinate. In contrast to χ XC, χ C is observed to concentrate in regions between atomic shells, from which information of nonclassical weak interactions can be obtained. Some relevant problems, in which the application of χ XC in conjunction with χ C would be of great value, are pr...
