The Lennard-Jones potential is often used in molecular dynamics simulations and drug-binding calculations to treat the London dispersion forces operating between two molecules as a function of distance r. It has two parameters, the well depth epsilon and the contact distance sigma. For the bromine molecule, compute the distance r in Angstroms at which the attractive portion of the L-J potential has diminished to an (absolute) value of RT (T=298K).
