ABSTRACT
In Chapter 8 we largely cast our discussion of the electronic structure of π-conjugated systems upon the idea that the C 2pz orbitals provided a good basis for the molecular orbitals. We also made the simplifying assumption that the atom-centered orbitals were orthogonal to each other. This approximation goes under the moniker of “neglect of differential overlap” (NDO) in the quantum chemical literature and “tight-binding approximation” in the solid-state physics literature. In this chapter, we shall continue along these lines in order to discuss transport and dynamics in extended systems.
