Antibonding molecular orbital - Wikipedia
...In theoretical chemistry, an antibonding orbital is a type of molecular orbital 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....

Molecular orbitals of H2 - lampz.tugraz.at
...The first excited state of an H 2 molecule has one electron in the bonding $\psi_+$ orbital and one in the antibonding $\psi_-$ orbital. This state will be split into a spin singlet and a spin triplet....

The hydrogen molecule ion ? Quantum Mechanics for Chemistry
...We construct trial wavefunction of the molecule from atomic orbitals. Applying variational method we find the two MOs to have distinct spatial profiles with one increasing probability of electron between the two nuclei and the other depleating. These MOs are called bonding and anibonding orbitals....

7.7 Molecular Orbital Theory ? Chemistry Fundamentals
...The bonding orbital is lower in energy than the original atomic orbitals because the atomic orbitals are in-phase in the molecular orbital. The antibonding orbital is higher in energy than the original atomic orbitals because the atomic orbitals are out-of-phase....

Molecular orbital diagram (MO) for H2, H2-, H2+, H22-, H22+, and Bond order
...A bonding molecular orbital (BMO) is formed by the linear combination of two AOs in the same phase. Contrarily, an antibonding molecular orbital (ABMO) is produced by the linear combination of two AOs in the opposite phase, counteracting the cohesive forces of the combining nuclei....

Bonding and antibonding orbitals - Chemistry LibreTexts
...These new orbitals arise from the linear combination of atomic orbitals to form bonding and antibonding orbitals. The bonding orbitals are at a lower energy than the antibonding orbitals, so they are the first to fill up. By figuring out the molecular orbitals, it is easy to calculate bond order....
