Hi, all,

I need to keep a molecule absolutely flat. I know about improper  
dihedrals (i.e. gi_1), but it doesn't seem to be enough to keep it  
flat.  It seems to get bent a little bit.  I have a system with a  
phenyl ring and protons and I am trying to run GROMOS 96 ff53a6 force  
field.  I appreciate your ideas.

Much appreciated,
