Intramolecular symmetry-adapted perturbation theory with a single-determinant wavefunction

Jérôme Florian Gonthier, Anne-Clémence Corminboeuf, Antonio Prlj, Ewa Maria Pastorczak

We introduce an intramolecular energy decomposition scheme for analyzing non-covalent interactions within molecules in the spirit of symmetry-adapted perturbation theory (SAPT). The proposed intra-SAPT approach is based upon the Chemical Hamiltonian of May ...

Practical Intramolecular Symmetry Adapted Perturbation Theory via Hartree-Fock Embedding

Jérôme Florian Gonthier, Anne-Clémence Corminboeuf

We develop a simple methodology for the computation of symmetry-adapted perturbation theory (SAPT) interaction energy contributions for intramolecular noncovalent interactions. In this approach, the local occupied orbitals of the total Hartree-Fock (HF) wa ...

Study of the Redox Properties of Singlet and Triplet Tris(2,2 '-bipyridine)ruthenium(II) ([Ru(bpy)(3)](2+)) in Aqueous Solution by Full Quantum and Mixed Quantum/Classical Molecular Dynamics Simulations

Ursula Röthlisberger, Ivano Tavernelli, Jérôme Florian Gonthier, Polydefkis Diamantis

The oxidation of ground-state (singlet) and triplet Ru(bpy)(3) were studied by full quantum-mechanical (QM) and mixed quantum/classical (QM/MM) molecular dynamics simulations. Both approaches provide reliable results for the redox potentials of the t ...

Exploration of zeroth-order Wavefunctions and Energies for Intramolecular Symmetry-Adapted Perturbation Theory

Jérôme Florian Gonthier, Anne-Clémence Corminboeuf

Non-covalent interactions occur between and within all molecules and have a profound impact on structural and electronic phenomena in chemistry, biology, and material science. Understanding the nature of inter-and intramolecular interactions is essential n ...

Adjusting the Local Arrangement of π‑Stacked Oligothiophenes through Hydrogen Bonds: A Viable Route to Promote Charge Transfer

Jérôme Florian Gonthier, Anne-Clémence Corminboeuf, Eric Albert Georges Bremond, Antonio Prlj, Hongguang Liu

We show that substituting quaterthiophene cores with strong H-bond aggregators, such as urea groups, provides an efficient way to adjust the mutual in-plane displacements of the semiconducting units and promote charge transfer. Our 2-D structure-property m ...

Ligand-Controlled Regiodivergent Pathways of Rhodium(III)-Catalyzed Dihydroisoquinolone Synthesis: Experimental and Computational Studies of Different Cyclopentadienyl Ligands

Baihua Ye, Jérôme Florian Gonthier, Anne-Clémence Corminboeuf, Matthew Wodrich, Nicolai Cramer

Rh-III-catalyzed directed C-H functionalizations of arylhydroxamates have become a valuable synthetic tool. To date, the regioselectivity of the insertion of the unsaturated acceptor into the common cyclometalated intermediate was dependent solely on intri ...

Modern computational approaches for quantifying inter- and intramolecular interactions

Jérôme Florian Gonthier

This thesis introduces modern computational approaches for quantifying and analyzing both intra- and intermolecular interactions. An original formalism to quantify intramolecular interactions ab initio is first introduced. Inspired from intermolecular Symm ...

Quantification of "Fuzzy" Chemical Concepts: A Computational Perspective

Jérôme Florian Gonthier, Anne-Clémence Corminboeuf, Matthew Wodrich

Chemists recurrently utilize "fuzzy'' chemical concepts (e.g. atomic charges, the chemical bond, strain, aromaticity, branching, etc.), which lack unique quantitative assessments but, nonetheless, are frequently employed as tools for understanding the intr ...

Four-electron oxygen reduction by Tetrathiafulvalene

Hubert Girault, Péter Kalman Péchy, Jérôme Florian Gonthier, Anne-Clémence Corminboeuf, Peiyu Ge, Astrid Johana Olaya Avendano

The four-electron reduction of oxygen by tetrathiafulvalene (TTF) in acidified 1,2-dichloroethane and at the acidified water/1,2-dichloroethane interface has been observed. Spectroscopy and ion transfer voltammetry results suggest that the reaction proceed ...

Branched Alkanes Have Contrasting Stabilities

Jérôme Florian Gonthier, Anne-Clémence Corminboeuf, Matthew Wodrich

Bond separation reactions of highly branched alkanes are used to assess (de)stabilizing interactions associated with various 1,3-nonbonded substituent patterns. While n- and singly methylated alkanes show positive bond separation energies (BSEs), which inc ...

How Strained are Carbomeric-Cycloalkanes?

Jérôme Florian Gonthier, Anne-Clémence Corminboeuf, Matthew Wodrich

The ring strain energies of carbomeric-cycloalkanes (molecules with one or more acetylene spacer units placed into carbon single bonds) are assessed using a series of isodesmic, homodesmotic, and hyperhomodesmotic chemical equations. Isodesmic bond separat ...
