## Abstract In standard treatments of atomic multipole models, interaction energies, total molecular forces, and total molecular torques are given for multipolar interactions between rigid molecules. However, if the molecules are assumed to be flexible, two additional multipolar atomic forces arise

โฆ Synopsis
The influence of conformational changes on the molecular charge distribution is investigated for three model compounds: We show that local torsional effects, such as rotations about bonds directly connected to the atom of interest, have an important influence on the atomic charge distribution. The description of the electrostatic potential of flexible molecules can be significantly improved if the torsional dependence of the multipole moments is described by a short Fourier series.

The quality of several atomic charge models based on different definitions has been analyzed using cumulative atomic multipole moments (CAMM). This formalism can generate higher atomic moments starting from any atomic charges, while preserving the corresponding molecular moments. The atomic charge c
