Opis

Charge Sensitivity Analysis (CSA) represents a linear response treatment of molecular systems, based upon the chemical potential and hardness/softness concepts established within density functional theory (DFT). Recently, it has been shown to provide an attractive framework leading to novel approaches to chemical reactivity of open systems. The monograph presents the conceptual and methodological basis of the CSA covering its DFT roots, alternative resolutions and representations, sensitivities of closed and open atomic and molecular systems, charge stability criteria and relaxational effects due to the system environment, and the maximum hardness principle, as well as alternative collective modes of charge redistribution. The CSA interaction energy in donor-acceptor systems is investigated in the second order approximation. In particular, the relaxational contributions to the chemical potential, hardness and softness quantities are examined and their physical implications are summarized. The charge sensitivity concepts for reactive systems include: one- and two- reactant reactivity criteria, mapping relations between equilibrium displacements in the electron population and nuclear position spaces, the intersecting state model of charge transfer processes, intermediate hardness decoupling modes and the minimum energy co-ordinates, all defined in the electron population space. Miscellaneous topics cover the CSA models of the chemical bond, aspects of the orbitally resolved theory, a role of frontier orbitals, and relation between local softness and chemical valence concepts. The conceptual developments are illustrated using recent qualitative and quantitative results on selected molecules, catalytic clusters and chemisorption systems. The CSA description is shown to connect directly to intuitive concepts and rules of chemistry, for example, those related to interactions between hard/soft acids and bases.
