### Intermolecular Potential Energy

In the formula for intermolecular potential energy, E , what does r stand for? Does it describe the distance between the two molecules, or the radius of one of the molecules?

This is important because I am trying to understand the parameters that contribute to IM energy and I am trying to derive these parameters from the formula. (i.e. I am trying to understand the relationship between E and size)

Hey! "r" is the distance between the two molecules
