molecular orbital theory in a sentence

Examples

1. In quantum chemistry he worked on semi-empirical molecular orbital theory and settling conjugated-circuit model on a firm quantum-mechanical basis.
2. 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.
3. 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.
4. 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.
