The two-center orbital picture that describes each of the two weak resonance contributors of
Concept introduction:
Overlap of atomic orbitals (AOs) can be thought of as wave interference. It can be constructive or destructive. Constructive interference increases the electron density between the two nuclei (an antinode) and results in a molecular orbital (MO) of lower energy. The phases of the overlapping orbitals are the same in this case. Destructive interference reduces the electron density between the two nuclei and results in an MO of higher energy. The phases of such AOs are the opposite. Since the electron density between the two nuclei decreases, there is a node (or a nodal plane) between the two atoms.
