The decrease in the number of antibonding electrons also strengthens the metal-ligand bond in transitions from a HS to LS state.
22.
The latter effect is due to charge depletion of the CO 5? bonding and charge increase of the CO 2? * antibonding orbital.
23.
As the internuclear separation increases, the molecule absorbs energy and the electronic wavefunction evolves to the antibonding state on the femtosecond timescale.
24.
This is because the argon atoms have a larger antibonding interaction with the 7s 1 electron, forcing it into a different subshell.
25.
The electron is transferred from the alkali metal ion to an unoccupied antibonding p-p ? * orbital of the aromatic molecule.
26.
Do those nucleophile electrons in fact, contribute to an antibonding orbital, that somehow negates the bonding between the LG and the carbon?
27.
But ? *, the antibonding orbital of a single bond, does look like you describe in the area between the two atoms.
28.
Half the difference in the number of antibonding and bonding electrons is the usual way to calculate the bond order of a localised bond.
29.
These electronic states differ only in the spin and the occupancy of oxygen's two antibonding ? g-orbitals, which are unpaired.
30.
In the staggered conformation, one C-H sigma bonding orbital donates electron density to the antibonding orbital of the other C-H bond.
