The Effect of Environment on the Band Structure of PolymersPolymers, especially biopolymers, are not found in a vacuum but exist rather surrounded by a medium (DNA and proteins are in an aqueous solution, with .. counterions in the case of DNA, and a smaller number of other ions around both). Hence it is important to consider the effect of the environment on the electronic structure of a (bio)polymer.

Excited and Ionized States of Polymerse, e.g., Ladik.) as the number of unit cells, ., approaches infinity:.In this way we are left with too large an excitation energy, because equation (8.1) for an infinite system reduces to the HF gap (which is too large anyway).
