“…[44] Numerous reviews are available that detail the theoretical principles underlying DFT together with its limitations, which include problems in modeling dispersion interactions and activation energy barriers in chemical reactions. [45] One important advantage of DFT, is that molecular systems composed of relatively large numbers of atoms can be treated completely quantum mechanically, allowing considerable insight into the electrostatic properties of MFx complexes and how these might be perturbed by being in a protein environment.…”

“…In our simple example, v R makes the delta function of the atom more negative, adds the attractive inverse cosh 4 potential between the atoms, and adds an attractive ghost delta function at the position of the other atom to force the wave function to decay sufficiently rapidly outside the molecule. In the limit of infinite separation v 1 + v R reduces to v 1 and v 2 + v R reduces to v 2 , except for |x| < a, where the attractive potential 11) persists. This potential has at least one additional bound state, but with binding energy less than |E 0 |.…”

“…The underlying theory, partition-theory (PT), was used to construct a formulation of chemical reactivity theory (CRT) [3] which, for the first time, is consistent with the underlying density-functional theory [8,9] and is richer in structure than the preexisting CRT [10][11][12][13].…”

“…El potencial quí-mico electrónico (μ) y la dureza molecular (η) son definidas como: 9 Figura 1. Mecanismo de reacción de la sustitución electrofílica aromática para halobencenos (1) El potencial químico es una propiedad global que caracteriza la tendencia de los electrones a escapar desde un sistema en equilibrio; formalmente es el multiplicador de Lagrange asociado con la constante de normalización de la TFD que integra la densidad electrónica con respecto a N, [9][10][11][12][15][16][17] también esta relacionado con la electronegatividad de Mulliken a través de la expresión μ = -χ. 18 Por otra parte, la dureza puede ser entendida como una resistencia a la transferencia de carga del sistema, 13,17,19,20 ambos μ y η son propiedades globales del sistema y dependen de N y v (r).…”
