Molecular orbitals, like atomic orbitals, are wave functions. Combinations of atomic orbitals results in constructive and destructive interference of the wavefunctions, Ψ. With MO's there can be any number of Ψ's involved and the Ψ's can be on any atom in the system Constructive interference combination of Ψ's in phase. This is called a BONDING molecular orbital (MO) Destructive interference combination of Ψ's out of phase. This is an ANTI-BONDING MO
