Excluding LJ Interactions

Dear all,

I am simulating self assembled monolayers and within each chain I have defined bond , angle and dihedral coefficients. I am wondering if in presence of both angle and dihedral coefficients, lennard jones forces are also applied because of the bond coefficient? How can I disable the lennard jones interactions for these groups.

try reading the lammps documentation, particularly the
part about the special_bonds command.
