Comparison of MO LCAO and free-electron results for the π-spectra of azacyclic compounds

  • Published:
Soviet Physics Journal Aims and scope

Abstract

Energy levels and π-electron transition energies have been calculated by the free-electron method for pyrazine, pyrimidine, pyridazine, s-triazine, and s-tetrazine. Allowance is made for the inductive effects of the N atoms by the introduction of additional potential wells at the sites of the N atoms. The results are compared with those from MO LCAO calculations.
