Electric Permittivity in Individual Atomic and Molecular Systems Through Direct Associations with Electric Dipole Polarizability and Chemical Hardness

Uproszczony widok
dc.abstract.enThe particular role in the interaction with external electromagnetic fields is played by local dielectric environment, hence the electric permittivity of a medium. This includes both the intramolecular screening effects as well the neighbor interactions with, i.e., solvent molecules, which conclude in modified electronic transport properties, i.e., of single-molecule junctions. Specific features of molecular (a few electron) systems require a unique approach to their characterization because transfer of just one electron alters the system significantly. Under these circumstances the electron–electron interaction depicted through a screening phenomenon in individual systems has been directly related to electric dipole polarizability and chemical hardness. The relation with these two fundamental electronic response functions quantifies a physical basis for field energy storage as associated with charge delocalization. This sheds new light on how the chemical reactivity affects behavior of molecular electronic devices. Moreover it might also serve to assess how electromagnetic fields can alter the reactivity or assist in catalysis.
