Likewise, Molecular Orbital Theory, sort of a " hybridization theory on steroids ", makes a perfect prediction of the " correct " structure of benzene.
44.
In parallel, molecular orbital theory was applied in a more approximate manner using some empirically derived parameters in methods now known as semi-empirical quantum chemistry methods.
45.
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.
46.
He realised that the then current approach to molecular orbital theory was incorrect and changed his topic to what resulted in the development of the Roothaan equations.
47.
The impact of valence theory declined during the 1960s and 1970s as molecular orbital theory grew in usefulness as it was implemented in large digital computer programs.
48.
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.
49.
In 1927 Mulliken worked with Hund and as a result developed his molecular orbital theory, in which electrons are assigned to states that extend over an entire molecule.
50.
A 2 + 2 cycloaddition reaction is one example of a pericyclic reaction that can be analyzed using these rules or by the related frontier molecular orbital theory.
