The Born-Huggins-Meyer potential (although looking at the authors/publications perhaps it would be more precisely known as the Born-Meyer-Huggins potential) [1] [2] [3] is given by [4]

where

  • is the intermolecular pair potential between two particles or sites
  • is the diameter (length), i.e. the value of at which

The first term is an exponential repulsion, followed by dipole-dipole and dipole-quadrupole dispersion terms. This potential is often augmented with a Coulombic interaction.

This potential is often used to study alkali halides.
