Self-Consistent Field Theory for the Electronic Structure of Polymers

Abstract

A general SCF–SCAO theory for computations of the electronic structure in polymeric species is presented. The theory is essentially a tight‐binding model expressed in a manner close to the self‐consistent field–LCAO matrix formalism and restricted to closed‐shell cases. Particular care has been taken to ensure a theory which can be easily applied in practical applications. A computer program, polymol, has been programmed and a short description is included at the end of this paper. Throughout the paper reference is given to the (H₂) infinite chain, as an example.
