[gmx-users] LJ-14 / LJ(SR)

[Juliette N.]

Hello everyone,

I know the following question has been discussed many times in the archive
but unfortunately I am still unclear about it therefore I would like to ask
for your patience.

I am interested in non bonded interactions, i.e LJ(SR) and it has been said
that LJ-14 potentials are *inter*molecular non bonded interactions. This
definition confuses me as I can't figure whether they have to be added up to
LJ(SR) (which as I understood correctly contains bonded 1-5, 1-6,...
interactions + all nonbonded interactions between atoms of different
molecules within Rc), or they are treated bonded interactions and must not
be added to LJ(SR). I would like to get a clear idea of the nature of these
types of interactions which I can't realize from the term '*inter*molecular
non bonded interactions".

Please briefly shed some light on this.
Thanks,
J.
