Molecular Orbital (MO) Theory is the final theory pertaining to the bonding between molecules. In contrast to VSEPR and valence bond theory which describe bonding in terms of atomic orbitals, molecular orbital theory visualizes bonding in relation to molecular orbitals, which are orbitals that surround the entire molecule. The purpose of MO theory is to fill in the gap for some behavior that cannot be explained by VSEPR and Valence-Bond Theory. Unfortunately, MO Theory can be the most difficult to understand and visualize, which is why we covered the other two first. As we mentioned in earlier posts, the way we determined the shape of orbitals is through Schrodinger's wave equation. It turns out that, according to the wave equation, orbitals can be one of two states. These states are often written as + + and − - , or drawn as different colors. For example, the p-orbitals are usually drawn with the two regions as different colors. We'll call this the "sign" of the orbital. s-orbitals
