It is found that pairs (dimers) of aromatic side chain amino acids preferentially align their respective aromatic rings in an off-centered parallel orientation, which is referred to as parallel displaced pi-stacking and is consistent with ab initio and molecular mechanics calculations of benzene dimer.
