We present the generalization of the effective oxidation state (EOS) method to assign oxidation states from wave function analysis to solid-state calculations. The scheme is realized in the framework of the Quantum Theory of Atoms in Molecules (QTAIM), and makes use of the atomic overlap matrices (AOM) of the atoms of the unit cell, expressed (whenever possible) in terms of maximally localized Wannier functions (MLWFs). The method is generally applicable to ionic solids or molecular crystals. The performance of the new method is assessed using a chemically diverse set of 40 solids, including simple metal oxides, perovskites, hydrides, and high-pressure systems with unusual bonding patterns.
期刊介绍:
The Journal of Chemical Theory and Computation invites new and original contributions with the understanding that, if accepted, they will not be published elsewhere. Papers reporting new theories, methodology, and/or important applications in quantum electronic structure, molecular dynamics, and statistical mechanics are appropriate for submission to this Journal. Specific topics include advances in or applications of ab initio quantum mechanics, density functional theory, design and properties of new materials, surface science, Monte Carlo simulations, solvation models, QM/MM calculations, biomolecular structure prediction, and molecular dynamics in the broadest sense including gas-phase dynamics, ab initio dynamics, biomolecular dynamics, and protein folding. The Journal does not consider papers that are straightforward applications of known methods including DFT and molecular dynamics. The Journal favors submissions that include advances in theory or methodology with applications to compelling problems.
