Local and Charge-Transfer Excitation of Pentacene-Buckminsterfullerene complexes

Ala Aldin M. Hani M. Darghouth, Omar A. Shareef, Firas A. AL-Lolage +1

The charge transfer state, the local excited state on pentacene, and the local excited state on buckminsterfullerene have been studied for four models of the pentacene-buckminsterf…

Diagrammatic Multiplet-Sum Method (MSM) Density-Functional Theory(DFT): III. Inclusion of Relaxation and Application to LiH

Mark E Casida, Abraham Ponra, Gadzikano Munyuki +1

Ideal density-functional approximations (DFAs) should account for dynamic, static, and nondynamic correlation. While common DFAs struggle with the latter two, the Ziegler-Rauk-Baer…

Diagrammatic Multiplet-Sum Method (MSM) Density-Functional Theory (DFT): II. Completion of the Two-Orbital Two-Electron Model (TOTEM) with an Application to the Avoided Crossing in Lithium Hydride (LiH)

Mark E. Casida, Abraham Ponra, Carolyne Bakasa +1

The Ziegler-Rauk-Baerends multiplet sum method (MSM) assumes that density-functional theory (DFT) provides a good description of states dominated by a single determinant. It then u…

Theoretical Study of Reactivity Indices and Rough Potential Energy Curves for the Dissociation of 59 Fullerendiols in Gas-Phase and in Aqueous Solution with an Implicit Solvent Model

Anne Justine Etindele, Abraham Ponra, Mark E. Casida +2

Buckminsterfullerene, C, has not only a beautiful truncated icosahedral (soccerball) shape, but simple Hückel calculations predict a three-fold degenerate lowest unoccupied…

Binding Energies for Successive Addition Reaction of .OH with C60 : A Laboratory for Testing Frontier Molecular Orbital Theory

Abraham Ponra, Anne Justine Etindele, Ousmanou Motapon +1

We study the successive addition reaction of .OH on fullerene C60. We confirm that the lowest energy isomers of C60(OH)n form a belt of hydroxyl groups around the equator of C60, b…
