## Abstract A new program for band structure calculations of periodic one‐dimensional systems has been constructed. It is distinguishable from other codes by the efficient two‐electron integral evaluation and the integration schemes of the density matrix in the first Brillouin zone. The computation

## Abstract Explicit functional forms for both the two‐electron Coulomb integral, (__aa∣bb__), and the one‐center core–orbital integrals, __Z__ (__aa__∣__Z__~__A__~), are derived which permit the penetration integrals to be fully derived and calculated. With these forms the ^3^Σ of the H~2~ molecul
