Hi, to the best of my knowledge, Molecular Dynamics is not the best way to study system stabilized by Pi-Pi or Pi-Cataion interaction. However,in MD people usually overpolarized C-C and C-H bonds to increase the quadrupole interactions, and thus, mimic the Pi-Pi interaction See

Dear Ivan, Thank you. I also think what you are saying that is right. I will also goes through the article. Thank you for article I actually run the system with simple Gromos96 5316 FF and amber 03 ff. I dont think it will help me With regards, Rama David On Thu, Oct 30, 2014 at 2:27

Dear justin, Thank you for suggestion. I did the docking of peptide ligand and receptor and I found the pi-pi and pi- cation interaction and hydrogen bond. Now if I do the MD it is hard to claim the pi-pi and pi-cation interaction through md. If I do the md will it help me ? will
