The presentation is designed to be accessible to anyone with intermediate undergraduate mathematics, physics and chemistry.
Dispersion forces may be repulsive or attractive. Dispersion forces are long-range and can be effective from large distance (>10nm) down to interatomic distances. The main features of dispersion force ( London dispersion force) is. In presenting a broad overview of the of the physical foundations of dispersion forces, the book provides theoretical, physical and synthetic chemists, as well as solid-state physicists, with a systematic understanding of the origins and consequences of these ubiquitous interactions. The principle aspect of dispersion force is the determination of the order of magnitude of the attractive force. It covers a wide range of system, from small intermolecular complexes, to organic molecules and crystalline solids, through to biological macromolecules and nanostructures. This book is an overview of current understanding of the physical origin and modelling of London dispersion forces manifested at an atomic level.
Recent years have seen the development of new, physically well-founded models, and dispersion-corrected density functional theory (DFT) is now a hot topic of research. They occur from either momentary interactions between molecules (the London dispersion force) or permanent electrostatic attractions between dipoles. This book is an overview of current understanding of the physical origin and modelling of London dispe London dispersion interactions are responsible for numerous phenomena in physics, chemistry and biology.
