van der Waals potential: an important complement to molecular electrostatic potential in studying intermolecular interactions

Multidimensional Intermolecular Potential Surfaces from Vibration- Rotation-tunneling (vrt) Spectra of Van Der Waals Complexes

The role of intermolecular forces in modern science is becoming ever more prominent, as increasing numbers of chemists and physicists turn to the investigation of condensed matter phenomena and biological systems. Although thee subject is hardly novel, the state of our knowledge of intermolecular forces and their associated potential energy surfaces is, nevertheless, remarkably primitive. For e...

Collective many-body van der Waals interactions in molecular systems.

Van der Waals (vdW) interactions are ubiquitous in molecules and condensed matter, and play a crucial role in determining the structure, stability, and function for a wide variety of systems. The accurate prediction of these interactions from first principles is a substantial challenge because they are inherently quantum mechanical phenomena that arise from correlations between many electrons w...

Tutorial 3: van der Waals Interactions

Van der Waals interactions with soft interfaces

Many naturally occurring microbiological and synthetic polymer systems have soft interfaces due, e.g., to the presence of polymer brushes at the surfaces. The initial interactions (before contact) in such systems are typically physical rather than chemical in origin, e.g. electrostatic or van der Waals forces. We calculate the form of the summed van der Waals interaction energies UHS and USS be...

van der Waals interactions across stratified media.

Working at the Lifshitz level, we investigate the van der Waals interactions across a series of layers with a periodic motif. We derive the complete form of the van der Waals interaction as an explicit function of the number of periodic layers. We then compare our result with an approximation based on an anisotropic-continuum representation of the stratified medium. Satisfactory agreement betwe...
