## Abstract For the Hirshfeld‐I atom in the molecule (AIM) model, associated single‐atom energies and interaction energies at the Hartree–Fock level are efficiently determined in one‐electron Hilbert space. In contrast to most other approaches, the energy terms are fully consistent with the partiti

Abstract
Based on the so‐called Hirshfeld atom in the molecule scheme, a new AIM method is presented. The method is similar to the Hirshfeld‐I scheme, with the AIM weight function being constructed by minimizing the information loss upon formation of the molecule, but now requiring explicitly that the promolecular densities integrate to the same number of electrons as the AIM densities. This new weight function leads to a new iterative AIM scheme, and the resulting operative scheme is examined and discussed. The final results indicate that the newly proposed method does not perform as well as the Hirshfeld‐I method.
