The Nobel Prize in Chemistry 2011 When Dan Shechtman entered the discovery awarded with the Nobel Prize in Chemistry 2011 into his notebook, he jotted down three question marks next to it. The atoms in the crystal in front of him yielded a forbidden symmetry. It was just as impossible as a football – a…

  John A. Pople has developed computational methods in chemistry. These are based on different descriptions of the wave function in the Schrödinger equation. He has created a theoretical model chemistry in which a series of increasingly refined approximations systematically approaches the exact solution to the quantum-mechanical equations. In this way it has become possible…

  The mechanisms of chemical reactions can be studied with quantum-chemical methods. The Schrödinger equation gives an energy for each molecular structure. The energy curve for a given reaction path, which passes through different intermediate states (minima) and transition states (maxima), shows whether that particular mechanism is possible. The diagram shows possible mechanisms for how…
