Anti-bonds in MO Diagram

Postby lorelrodriguez4c » Mon Oct 31, 2016 1:21 pm

Can someone further explain what anti- bonds , signified by "*" on the MO Diagram, means? I remember that it is related to the location of the electrons in between the nucleus, but I am not entirely sure of its significance. Thank you!

Anti-bonds are basically the molecular orbital formula where the two orbital functions are subtracted. This is so the number of atomic orbitals are conserved: start off with 2 atomic orbitals, and then create one 'Bonding' and one 'Anti-Bonding'. This is on page 106-107 in the course reader :)

Anti-bonding MO occurs when atoms are "out of phase" which means you subtract the wave functions, bonding MO happens when atoms are "in phase" which means you can add the wave functions.
