# Hertzian sphere model

The **Hertzian sphere model** is given by ^{[1]} (Eq. 1):

where is the intermolecular pair potential, is the distance between site 1 and site 2. represents a length scale and an energy. In the limit this potential becomes the hard sphere model. For example, for the potential looks like
