PDF Calculating the Energies of Molecular Orbitals much of each atomic coefficient is required to make each of the molecular orbitals. The coefficients for the highest energy MO wavefunction is solved below. Repeat these calculations for determining the coefficients of this molecular orbital, but then go on to calculate the coefficients for the other two MO's in our HF molecule. MolecularOrbitals - Maple Help - Waterloo Maple In the LCAO approach, molecular orbitals are constructed by selecting sums and differences of atomic orbitals. For example, for hydrogen fluoride, we start with the H1s, F1s, F2s, F2px, F2py, and Fp2z orbitals. A linear combination of H1s and F2pz orbitals creates a bonding σ orbital and antibonding σ∗ orbital.
