Development and Applications of the Density-Based Theory of Chemical Reactivity [PDF]

open access: yesThe Journal of Physical Chemistry Letters, 2022
Density functional theory well-recognized by its accuracy and efficiency has become the workhorse for modeling the electronic structure of molecules and extended materials in the past decades. Nevertheless, how to establish a density-based conceptual framework to appreciate bonding, stability, function, reactivity, and other physiochemical properties ...

Phenomenological chemical reactivity theory for mobile electrons [PDF]

open access: yesTheoretical Chemistry Accounts, 2009
We present herein a model to deal with the chemical reactivity, selectivity and site activation concepts of π electron systems derived by merging the classical Coulson–Longuet-Higgins response function theory based on the Huckel molecular orbital (HMO) theory and the conceptual density functional theory. HMO-like expressions for the electronic chemical

Volume-based thermodynamics approach in the context of solid-state chemical reactivity analysis

open access: yes, 2023
Reactivity belongs to the objects of theoretical chemistry in the broadest sense, as it embodies both thermodynamic and kinetic factors. Volume-based thermodynamics (VBT) is a successful tool for the prediction of solid-state chemical reactivity of ...
