1. | Introduction to Hartree-Fock Molecular Orbital Theory Physical Meaning of the Terms. Each pair of electrons (in orbitals i and j) has also has an “ Exchange integral”: This is like the Coulomb integral. Except two of the orbital indices have been. “exchanged”!

2. | Evaluation of the Coulomb and exchange integrals for higher - arXiv The Coulomb and exchange integrals are evaluated via spherical harmonics. The interaction of the magnetic moments of the electrons between them, was taken into account through a cosine term in the Coulomb potential.Tags:coulomb and exchange integrals |

5. | Lecture 21-22, Helium Atom - MIT OpenCourseWare These integrals are called Coulomb(J) and exchange(K) integrals, respectively. Both are positive numbers (because they arise from electron repulsion). The coulomb integral is so named because we can re-write itTags:coulomb and exchange integrals |
