Índices de reatividade química a partir da teoria do funcional de densidade: formalismo e perspectivas/ Chemical reactivity indexes from density functional theory: formalism and perspectives

Duarte, Hélio Anderson

Resumo em inglês The fundaments of the modern Density Functional Theory (DFT), its basic theorems, principles and methodology are presented. This review also discuss important and widely used concepts in chemistry but that had not been precisely defined until the development of the DFT. These concepts were proposed and used from an empirical base, but now their precise definition are well established in the DFT formalism. Concepts such as chemical potential (electronegativity), hardness, (mais) softness and Fukui function are presented and their consequences to the understanding of chemical reactivity are discussed.
