I can second that; Chiu's parameters are not only good for bilayers,
but the nice thing is that they are parameterized in order to get
correct densities and heat of vaporization for all chain lengths
ranging from ethane to pentadecane (the alternative is Oliver Berger's
parameters, which are very good for pentadecane, but not shorter
A diploma student of ours (Jakob Wohlert) repeated Chiu's idea but for
the Gromos96 force field; these parameters are included in the ffg43a2x
forcefield in the contributions section, although I haven't tested it a
