LJ-SR are normal nonbonded interactions within the short-range cutoff.  LJ-14 
are, by definition, intramolecular interactions occurring between 1-4 pairs. 
Whether or not such a decomposition has any physical meaning depends on whether 
or not the force field parametrization assigns them any meaning.
