Frontier Hybrid Orbitals . II . Applications

In this paper, the frontier hybrid orbitals (FBO's) of a series of octahedral ML5 fragments are used to discuss the electronic structure and the chemical bond of these fragments and the molecules built of these ML5 fragments. The bond orbitals which are chosen as the linear combination of the frontier hybrid orbitals . of fragments are calculated and explain the electronic structure and propert...

Frontier Hybrid Orbitals . III . Study on SN 2 Reactions *

where Xis called the nucleophile, RjR2R3ZY the substrate and Ythe leaving group. The substrate structure, the nature of the nucleophile, of the reaction center Z and of the leaving group, and the nature of the solvent are important factors of the overall rate of reaction. Now, experimentsare available for studying solvated ions in the gas-phase, it is possible to explore the transition state in...

Theoretical unification of hybrid-DFT and DFT plus U methods for the treatment of localized orbitals

Hybrid functionals serve as a powerful practical tool in different fields of computational physics and quantum chemistry. On the other hand, their applicability for the case of correlated d and f orbitals is still questionable and needs more considerations. In this article we formulate the on-site occupation dependent exchange correlation energy and effective potential of hybrid functionals for...

DFT Estimation of Exchange Coupling Constant of Cr8 Molecular Ring using the Hybrid Functional B3LYP

A study of electronic and magnetic properties of an octametallic chromium-based homonuclear molecule Cr8F8(CO2 −C(CH3)3)16 is presented, using density functional theory (DFT) approach and linearized augmented plane wave (LAPW) method with Perdew, Burke and Ernzerhof (PBE) and Becke 3-term correlation (B3LYP) functionals. The exchange coupling parameters between transition metals ions are extrac...

Frontier Hyhrid Orbitals . I . Principles *

The purpose of the present paper is to describe a method, in quantitative sense, of discussing the isolobal analogy of fragments (or molecules) proposed by Hoffmann. The »Frontier Hybrid Orbitals (FHO)« are used to represent the directional, fronti er orbitals of the central atom, which have the same meaning as the »lobes« involved in the concept of isolobal analogy. The calculatio n of Frontie...
