1. Planetary orbital theory is long established fact, still taught in the universities. 2. Molecular Orbital Theory predicts two pi bonds, see this molecular orbital diagram. 3. As for atoms, see electron configuration for an overview of orbital theory . 4. Some, using either hybridization theory or molecular orbital theory predicts a double bond. 5. In molecular orbital theory , this leads to molecular orbitals that are singly occupied. 6. Zimmerman gave ACS Short Courses on organic quantum chemistry and molecular orbital theory . 7. Afterward, he developed mathematical formulas to enable the progress of the molecular-orbital theory . 8. Frontier molecular orbital theory can be used to explain this outcome. 9. Covalent bonds are better understood by valence bond theory or molecular orbital theory . 10. Computer modeling of molecular orbital theory indicates that this bonding involves only s-and p-orbitals.
