"WebThe formulation of the wavefunction in a basis leads to the so-called Roothaan equations which are obtained from the HF equations by inserting the expansion (2.7) into (2.4), multiplying from the left by the set of basis functions and integrating over the spatial coordinates. This procedure leads to the following integral matrix equation. " - Roothann

The Roothaan equations are a representation of the Hartree–Fock equation in a non orthonormal basis set which can be of Gaussian-type or Slater-type. It applies to closed-shell molecules or atoms where all molecular orbitals or atomic orbitals, respectively, are doubly occupied. This is generally called Restricted Hartree–Fock theory. The method was developed independently by Clemens C. J. Roothaan and George G. Hall in 1951, …
