Our 2nd Annual Scheuermann's Disease Fundraiser on the afternoon of Sunday October 4th has now been posted to the VisitPitsburgh website. ... VisitPittsburgh is a website designed to help people plan their next visit to Pittsburgh, PA.
An antibonding orbital is a molecular orbital containing an electron outside the region between the two nuclei. As two atoms approach each other, their electron orbitals begin to overlap. This overlap forms a molecular bond between the two atoms with its own molecular orbital shape.
A non-bonding orbital (NBMO) is a molecular orbital that does not contribute to the energy of the molecule. Molecular orbitals come from the linear combination of atomic orbitals. In a simple diatomic molecule such as HF, F has more electrons than H. The s orbital of H can overlap with the #2p_z# orbital of fluorine to form a bonding Ï and an antibonding Ï* orbital. The #p_x# and #p_y# orbitals from the F do not have any other orbitals to combine with. They become NBMOs. The #p_x# and #p_z# atomic orbitals have become molecular orbitals.
