A polarizable quantum mechanics and molecular mechanics model has been extended to account for the difference between the macroscopic electric field and the actual electric field felt by the solute molecule. This enables the calculation of effective microscopic properties which can be related to mac ...

We will restrict ourselves to the case of a uniform planar charge distribution of infinite extent: in other words, a flat sheet with a uniform surface charge density that extends to infinity. These restrictions make the resulting electric field especially simple ...
