    • One problem encountered in this context is if the self consistent field (SCF) cycle converges faster than the dipole of the system. In this case, the calculation stops before the final, correct value for the dipole is obtained. Thus, if necessary, additional SCF cycles were performed at the optimized geometries to achieve a convergence also of the unit cell dipole moment to less than 0.01 eÅ

    • Since it is not sensible to calculate the bend of the molecules at non-equilibrium distances, all calculations were done forcing the molecule into their planar, gas phase geometry. The electronic structure in all cases has been calculated at the GGA level

    • This equation can be derived by combining the Poisson equation with the Helmholtz equation (eq 3, It can be shown that, due to the integration over the whole unit cell and the resulting boundary conditions for the charge rearrangements, this definition of μBond is equivalent to the more conventional definition as μBond,z= ∫ uz ρ(z)z dz
    • Bond,z= ∫ uz ρ(z)z dz.
