Information-Theoretic Perspectives on Chemical Problems: Recent Developments and Applications [PDF]

open access: yesEntropy
Information-theoretic approach (ITA) has emerged as a powerful density-based framework for interpreting molecular structure, stability, and reactivity within density functional theory (DFT). By treating the electron density as a probability distribution,

New Dual Descriptor for Chemical Reactivity

open access: yesThe Journal of Physical Chemistry A, 2004
In this paper, a new dual descriptor for nucleophilicity and electrophilicity is introduced. The new index is defined in terms of the variation of hardness with respect to the external potential, and it is written as the difference between nucleophilic and electrophilic Fukui functions, thus being able to characterize both reactive behaviors.

Heterogeneous Intramolecular Electric Field as a Descriptor of Diels–Alder Reactivity [PDF]

open access: yesThe Journal of Physical Chemistry A, 2020
External electric fields have proven to be an effective tool in catalysis, on par with pressure and temperature, affecting the thermodynamics and kinetics of a reaction. However, fields in molecules are complicated heterogeneous vector objects, and there is no universal recipe for grasping the exact features of these fields that implicate reactivity.

Glycerol and malonic acid as corrosion inhibitors seen through the density functional theory perspective [PDF]

open access: yesJournal of the Serbian Chemical Society, 2022
Glycerol (G) is the major co-product in the transesterification process of biodiesel. As clean energy demand increases, the production of G also increases and new ways of re-using it are needed.

On the influence of dynamical effects on reactivity descriptors [PDF]

open access: yesChemical Physics Letters, 2019
Abstract In this paper, we investigate the role of structural dynamical effects on reactivity properties of selected Michael acceptors. To this aim, quantum molecular dynamics simulations were performed. Conceptual density functional theory descriptors were then evaluated on selected snapshots, providing statistical indicators suitable to assess the ...
