The image displays the electrostatic potential at a distance of 6.75 angstroms from the center of the dipole of a small prototypical drug, meta-fluorobenzoic acid. The electrostatic potential is color-mapped onto a sphere, while the molecular dipole (red) and the principal axes (blue) of the quadrupole tensor are represented as arrows. This image gives nearly complete representation of the electrostatics in the immediate vicinity of the molecule.
