Persistence of atoms in molecules: there is room beyond electron densities
IUCrJEvidence that the electronic structure of atoms persists in molecules to a much greater extent than has been usually admitted is presented. This is achieved by resorting to N-electron real-space descriptors instead of one- or at most two-particle ...
