In reply to Mark's comment, it used to be that one could specify separate LJ 1-4 interactions as he suggests, but there is no route to do this for Coulmb 1-4 scaling. Perhaps that haas changed in more recent versions of gromacs. If not, you might consider a variant of the approach that we used ages ago for combining lipid and protein force fields (Berger and OPLS) that have different scaling rules: http://pomes.biochemistry.utoronto.ca/files/lipidCombinationRules.pdf

Subject: [gmx-users] mixed 1-4 scaling factor
I want to simulate a system using Amber and Glycam force fields together
with gromacs, I am wondering whether
a scheme of mixed 1-4 scaling factors is available with Gromacs.
I searched the mailing list, and I found this post which no one responded:
And I also found this post, but it is not very clear.
Could someone give me some tips on the problem? Thanks very much!
All the best,
