摘要: Part I : A new technique is developed for evaluating the integrals which occur in molecular theory. The method based on expansion of exponentials terms so-called £ functions. These involve modified Bessel In this part we list properties these functions needed two-centre integrals. table provided ’s and K used their tabulation. An account given certain some numerical examples are provided. II Methods described evaluation two-centre, one-electron Coulomb, overlap resonance integrals, two-electron Coulomb hybrid (Coulomb-exchange) penetration Formulae listed more than 180 distinct
