Distributed dispersion: A new approach

Distributed polarizability and dispersion models can be constructed by analyzing the response, at each point in an array surrounding the molecule, to the field due to a point charge at each point of the array in turn, in an extension of the method described by Dehez [Chem. Phys. Lett. 338, 180 (2001)]. Anisotropic distributed polarizabilities and anisotropic distributed C-6 dispersion coefficients have been calculated for carbon dioxide, water, benzene and ethane.
