To comprehend the nature of these forces, it is necessary to first comprehend the concepts of dipole, polarization, and polarizability. What is a dipole and what are polar molecules? The term dipole refers to something that has two oppositely charged points. In chemistry, a dipole structure is...

A weak, short-range attractive force between atoms or molecules caused by their dipole moments, often arising in otherwise nonpolar atoms or molecules from a temporary...
London dispersion forces are the weakest component of Van der Waals interactions. They arise from attractions between instantaneously induced dipoles on neighbouring atoms. Their relative weakness, in particular for light atoms, such as hydrogen, has led to their importance being largely ignored in disc...

By using the theory of intermolecular forces, two new expressions for Pauli repulsion and dispersion contributions to the solvation free energy are derived. These expressions contain explicitly the solute electron density and, therefore,... C Amovilli,B Mennucci - 《Journal of Physical Chemistry B》...
