Electronic Motion in the Mean Field Atoms and Molecules

Electronic Motion IN THE Mean Field Atoms and Molecules 

What is the electronic structure of atoms How do atoms interact in a molecule l vo neutml moieties (say. hydrogen atoms) attract each other with a force of a similar order of magnitude to the Coulombic forces between two ions. This is quite surprising. What pulls these neutral objects to one another These questions are at the foundations of chemistry. 

Computational technique atomic orbitals as building blocks of the molecular wave 

Excitation energy, ionization potential, and electron affinity (RHF approach) (A) p. 389 

The Born-Oppenheimer (or adiabatic) approximation is the central point of this book (note its position in the TREE). Thanks to the approximation, we can consider separately two coupled problems concerning molecules
