Experimental quantum chemistry and chemical reactivity (Chapter 17)

open access: yes, 2023
This chapter describes a framework for chemical bonding analysis called Experimental Quantum Chemistry (EQC). In EQC, energies of atoms and molecules are partitioning into terms that can be both quantum mechanically calculated and experimentally ...

Density-based Reactivity Theory Applied to Excited States [PDF]

open access: yes, 2023
Excited states are essential to many chemical processes in photosynthesis, solar cells, light-emitting diodes, and so on, yet how to formulate, quantify, and predict physiochemical properties for excited states from the theoretical perspective is far ...

Applications of the Conceptual Density Functional Theory Indices to Organic Chemistry Reactivity

open access: yesMolecules, 2016
Theoretical reactivity indices based on the conceptual Density Functional Theory (DFT) have become a powerful tool for the semiquantitative study of organic reactivity. A large number of reactivity indices have been proposed in the literature.

Valence atom with bohmian quantum potential: the golden ratio approach

open access: yesChemistry Central Journal, 2012
Background The alternative quantum mechanical description of total energy given by Bohmian theory was merged with the concept of the golden ratio and its appearance as the Heisenberg imbalance to provide a new density-based description of the valence ...
