Reactivity theory
Webtheory of orbitals for that purpose is most nicely mentioned in a lovely and unique book of Jorgensen and Salem(Ref. 32). In relation to such a qualitative reactivity theory the frontier orbital polarization approach is frequently convenient for the reaction design. The orbital interaction causes orbital polarization in the course of reaction. WebOct 28, 2024 · Description. Chemical Reactivity in Quantum Mechanics and Information Theory introduces a thermodynamic-like description of molecular systems and provides an objective treatment of their fragments.
