Molecular Orbitals Explained

The variational principle is a powerful tool that allows for the derivation of equations for molecular orbitals, previously an enigma. By utilizing the Fock operator, a set of equations emerges, known as the Hartree-Fock equations, which can be solved to uncover the energies of molecular orbitals. This process ultimately leads to the construction of the total molecular wave function, shedding light on the fundamental nature of molecular structures.
