How to use the two-center Lennard-jones potential in LAMMPS?

I’ve read a paper about two-center Lennard-Jones potential (2CLJ) calculate the subcooled liquid oxygen. “Thermal conductivity of subcooled liquid oxygen.” (doi:10.1016/j.cryogenics.2005.05.004)
The molecule is assumed to be rigid. The distance between the interaction sites of one molecule is constant. So, anyone knows how to use the two-center Lennard-jones potential in LAMMPS?
