This isn't really part of Gromacs or GROMOS , but a user-contributed
forcefield. I happen to know since it was done by a diploma worker in my old
group :-) Try to contact jakob at theophys.kth.se and ask him - the general idea
is that the carbons have been reparametrized to reproduce density and heat of
vaporization for long hydrocarbon chains. Similar changes are being introduced
in the GROMOS forcefield in Zurich, but it's not yet part of their distributed
files, I think.
