[LAMMPS] - Assign charge between atoms

Dear colleagues,

I’m new here in the group.

I would like to know how I could put a charge in the middle of a bond of atoms (a charge offset, i mean)?

Suppose I have an A-B bond, I would like to place a charge in the middle of the A-B bond.

What would be the approach to do this? What types of commands could I use?

Thanks for your time.

it is not quite clear what you are asking for.
initial positions and geometries can be defined through a data file.

can you explain in more detail what you are trying to model and what should happen to the forces on those additional charges?
