Contrary to our previous model, where computing all intramolecular interactions can be avoided since they cancel out when calculating interaction energies, this is no longer the case if we allow the molecules in our system to become polarized. This is a direct consequence of the intramolecular interaction energy components being dependent of what surrounds every molecule in our system. Therefore, the energies of each molecule when isolated need to be calculated, only once, and then subtracted to the total energy, that is, intra and intermolecular interaction energies where the latter is disregarded in our previous model due to it cancelling as consequence of its, inaccurate, non-polarizability.
