Force Interactions between species in LAMMPS

Hi,

I am a new LAMMPS user. I would like to know for a simulation involving two species, A and B, is there a way I can know the value of individual Potential and Force interactions between species A-A and A-B. This is because, I would like to add a module to LAMMPS which would use these (Force_AA and Force_AB) values and do some scaling based on that.

Please let me know if my query doesnt seem clear.

Thanks,

Peetak
