A Molecular Electron Density Theory Study of the Synthesis of Spirobipyrazolines through the Domino Reaction of Nitrilimines with Allenoates. [PDF]

open access: yesMolecules, 2019
The reaction of diphenyl nitrilimine (NI) with methyl 1-methyl-allenoate yielding a spirobipyrazoline has been studied within molecular electron density theory (MEDT) at the MPWB1K/6-311G(d) computational level in dichloromethane. This reaction is a domino process that comprises two consecutive 32CA reactions with the formation of a pyrazoline ...

A molecular density functional theory approach to electron transfer reactions

open access: yesChemical Science, 2019
International audienceBeyond the dielectric continuum description initiated by Marcus theory, the standard theoretical approach to study electron transfer (ET) reactions in solution or at interfaces is to use classical force field or ab initio molecular ...

Graph2Mat: universal graph to matrix conversion for electron density prediction [PDF]

open access: yesMachine Learning: Science and Technology
The electron density is a fundamental observable of an atomic system from which all ground-state properties can be computed. As a prediction target for machine learning (ML) models, electron density is often represented on a dense real space grid, which ...

A Density Functional Theory for the Average Electron Energy [PDF]

open access: yes, 2022
A formally exact density functional theory (DFT) determination of the average electron energy is presented. Our theory, which is based on a different accounting of energy functional terms, partially solves one well known downside of conventional Kohn ...

Multiconfiguration Pair-Density Functional Theory for Chromium(IV) Molecular Qubits [PDF]

open access: yes, 2022
Pseudo-tetrahedral organometallic complexes containing chromium(IV) and aryl ligands have been experimentally identified as promising molecular qubit candidates. Here we present a computational protocol based on multiconfiguration pair-density functional
