The attractive force draws molecules closer together and gives a real gas a tendency to occupy a smaller volume than an ideal gas. Which interaction is more important depends on temperature and pressure (see compressibility factor). In a gas, the distances between molecules are generally large, so intermolecular forces have only a small effect.

Therefore, the Mie potential is a more flexible intermolecular potential than the simpler Lennard-Jones potential. The Mie potential is used today in many force fields in molecular modeling . Typically, the attractive exponent is chosen to be m = 6 {\textstyle m=6} , whereas the repulsive exponent is used as an adjustable parameter during the ...
Van der Waals forces include attraction and repulsions between atoms, molecules, as well as other intermolecular forces.They differ from covalent and ionic bonding in that they are caused by correlations in the fluctuating polarizations of nearby particles (a consequence of quantum dynamics [6]).
London dispersion forces (LDF, also known as dispersion forces, London forces, instantaneous dipole–induced dipole forces, fluctuating induced dipole bonds [1] or loosely as van der Waals forces) are a type of intermolecular force acting between atoms and molecules that are normally electrically symmetric; that is, the electrons are ...
Intermolecular forces are experienced by molecules when they are within physical proximity of one another. [20] [21] These forces are very important for properly modeling molecular systems, as to accurately predict the microscopic behavior of molecules in any system, and therefore, are necessary for accurately predicting the physical properties ...
The ideal gas model tends to fail at lower temperatures or higher pressures, when intermolecular forces and molecular size becomes important. It also fails for most heavy gases, such as many refrigerants, [2] and for gases with strong intermolecular forces, notably water vapor. At high pressures, the volume of a real gas is often considerably ...
