    • The linear structure of an arginine monomer is a stationary point on the potential energy surface when performing a geometry optimization on a RI-MP2/TZVPP(aug) level of theory. For the dimer system the hydrogen atoms involved in the H-bond had to be kept fix during the geometry optimization (B3LYP/6-3-11-H-G**) since the strong charge interaction mediated through a single hydrogen bond leads to a proton transfer from the guanidinium group towards the carboxylate oxygen. The geometry optimization for the 2-(guanidiniocarbonyl)-1H-pyrrole-5-carboxylate dimer was performed on a RI-MP2/TZVPP level of theory with augmented basis functions for the carboxylate oxygens. For the optimization of the monomeric 2-(guanidiniocarbonyl)-1H- pyrrole-5-carboxylate only a standard TZVP basis could be employed since an enlargement of the basis set causes a proton transfer from the pyrrole ring to the carboxylic group (see Figure 9) in gas phase
