Besides the already mentioned Fukui function, there are a couple of other commonly used concepts which can be connected with Density Functional Theory (Chapter 6). The electronic chemical potential p is given as the first derivative of the energy with respect to the number of electrons, which in a finite difference version is given as half the sum of the ionization potential and the electron affinity. Except for a difference in sign, this is exactly the Mulliken definition of electronegativity. ... [Pg.353]

The definition of the hardness t] according to the density functional theory easily demonstrates the essence of this parameter. According to Klopman [8], the potential I and electron affinity F can be expressed through the energies of boundary orbitals upper occupied (T) and lower vacant (L) ones... [Pg.17]

Density functional theory (DFT) has emerged as a powerful technique for the solution of the Schrodinger equation at affordable computational costs. Several groups have used DFT to address the effect of electron correlation in ion-water systems. Combariza and Kestner studied short-range interactions and charge transfer in mono and tri-hydrates of Li", Na", F, and CF. The accuracy of their DFT predictions was assessed by comparing electron affinity and atomic polarizability to experimental values. Small water and ion-water clusters were also analyzed and compared to those predicted by effective potentials in MD simulations. [Pg.433]
