On the other hand, an analysis within quantitative molecular orbital theory shows that 2-orbital-4-electron ( steric ) repulsions are dominant over hyperconjugation.

He has also authored popular undergraduate textbooks on spectroscopic methods of structure determination, organic synthesis, and applications of frontier molecular orbital theory to problems in organic chemistry.
43.
With more complicated compounds, such as metal complexes, valence bond theory is less applicable and alternative approaches, such as the molecular orbital theory, are generally used.
44.
The Lewis structure O = O does not accurately represent the diradical nature of molecular oxygen; molecular orbital theory must be used to adequately account for the unpaired electrons.

"' Zero differential overlap "'is an approximation in computational molecular orbital theory that is the central technique of semi-empirical methods in quantum chemistry.
46.
The molecular orbital theory considers that endo transition state, instead of the exo transition state, is favored ( "'endo addition rule "').

Streitwieser was one of the pioneers of molecular orbital theory and his book " Molecular Orbital Theory for Organic Chemists " had a lasting impact on the field.

Ligand field theory, introduced in 1935 and built from molecular orbital theory, can handle a broader range of complexes and can explain complexes in which the interactions are covalent.
50.
According to the molecular orbital theory, the HOMO of the ligand should have an energy that overlaps with the LUMO ( Lowest Unoccupied Molecular Orbital ) of the metal preferential.
