TTie degree of coverage, 6, is related to the surface excess concentration, F, by 6= /yrwL where /ml denotes the surface excess concentration of a Meads monolayer. The parameter c represents the number of first nearest neighbors in the compact Meads monolayer. The lateral interaction parameter, a, is related to the lateral interaction energy, i Meads-Meads. by = l Meads-Meads electrode potentials E... 

The optical absorption spectra of organic molecular solids are characterized by two kinds of intermolecular interaction energy, i.e., the Coulombic energy and the resonance interaction energy (Davydov, 1962, 1971). The former energy induces...

Figure 16.2 Potential energy curves for the dissociation of the covalent bond in CI2 (UTPSS-D3/def2-QZVP DFT level of theo7) and the van der Waals bond in Atj. A reduced interaction energy (i.e., setting the equiiibrium value to —1) and shifted distances (setting = 0) are...

To solve these equations two terms have to be provided from experimental data, i.e., the two differences involving the interaction energies, ) i,b ab > which are generally not predictable. The variables v°l v l are the molar volumes of the pure components. The major advantage of the Wilson equations is that they render... 

Yet another way to decompose the electronic interaction energy, i.e., charge transfer plus polarization energies, is based on symmetry. Only A- and B-orbitals belonging to the same irreducible representation will interact. This is the basis for the widely used distinction between, e.g., tr-donation and 7r-backdonation. It is indeed possible to write the total electronic interaction energy as the sum of contributions from the irreducible representations. We may write ... 

In this case, the theory of the Ising model can still be retained with a rescaling of the pairwise interaction energies, i.e., besides the factor IF(cavity) we must replace Si+i) with U Si, i) + 5A Si, Si+i). This is what is usually assumed in the theory of polymers, proteins, etc., in a solvent. 

Hamaker. The contribution of the surface extension energy and/or bending elasticity to the pair interaction potential is also included. The extension of the drop surface upon the deformation corresponds to a soft interdroplet repulsion. All the remaining possible interactions (electrostatic, steric, depletion, etc.) can usually be treated in the framework of Deqaguin s approximation, which allows one to account for the two contributions of the total interaction energy (i) across the flat film and (ii) between the spherical surfaces surrounding the fllm. " Combined with relevant expressions for the hydrodynamic interactions, this approach could be used for studying the coalescence of Brownian emulsion and microemulsion droplets. ...
