Basis Sets Used in Molecular Orbital Calculations

Each molecular orbital (one electron function) ψi is expressed as a linear combination of n basis functions Φμ. By convention, molecular orbitals are abbreviated by the greek letter ψ (psi), while the basis functions are symbolized by the greek letter Φ (phi). ψi = Σ n μ=1 cμi Φμ (2)
