The quantum theory applied to biology

Quantum Chemistry Theory

Molecular Structure Theory

Molecular Structure Theory applies the laws of quantum physics to a molecular model. The theory assumes that matter is essentially a gas of electrons and atomic nuclei. This results in a set of mathematical equations that can be solved approximately. The principal result of this calculation is the electronic wave function that describes all properties of a molecule.

Chemical Reactivity

Chemical reactivity has first been defined based on experimental observation. The electronic wave function can be calculated directly from first principles. Several properties of the electronic wave function relate to chemical reactivity. The theory of chemical reactivity is a bridge between quantum physics and experimental (bio)chemistry.
