Electrons in a nonbonding molecular orbital are higher in energy than in a bonding molecular orbital, but lower in energy than electrons in an antibonding molecular orbital. In this simplified diagram of the pi molecular orbitals of the allyl carbocation , π 1 is a bonding molecular orbital because it contains two in-phase p orbital overlaps and no out-of-phase p orbital overlaps.

The bonding π MO (molecular orbitals) of an aromatic compound are fully occupied, while the antibonding and non-bonding π MO are fully unoccupied. Whether

Av de möjliga The pi* is more antibonding than the pi is bonding, due to electronic repulsion. See Fleming, “Frontier Orbitals and Organic Chemical Reactions” (chapter 2) for the clearest and best treatment of molecular orbitals in organic chemistry. In chemical bonding theory, an antibonding orbital is a type of molecular orbital (MO) that weakens the chemical bond between two atoms and helps to raise the energy of the molecule relative to the separated atoms. Such an orbital has one or more nodes in the bonding region between the nuclei.

More detailed MO description of ethene Molecular orbital theory has been very successfully applied to large conjugated systems, especially those containing chains of carbon atoms with alternating single and double bonds.

Archived Lecture Notes #2 (PDF), Section 3 "Pi" antibonding molecular orbitals This is a calculated solution for the constructive interference result. If destructive interference represents the orbital in which the electron happens to be found, the linear combination results in a depeletion of electron density between the positively charged protons.

That means that the jump from an oxygen lone pair into a $\pi$ anti-bonding orbital needs less energy. That means it absorbs light of a lower frequency and therefore a higher wavelength. For example, ethanal can therefore absorb light of two different wavelengths: the $\pi$ bonding to $\pi$ anti-bonding absorption peaks at 180 nm.
