Hi Phoebe,
I encountered a similar situation during my thesis work.
Maybe these
references can help:

Unusual
Arginine-Arginine Short-Range Interactions to Stabilization and
Recognition in Proteins." J. Protein Chem. 13(2): 195-215.

polarizability on
the potential of mean force of two cations. The
guanidinium-guanidinium ion pair in water." J. Phys. Chem. B

Phoebe,
You mean something like what is found in Figure 2b?

This paper describes a functionally important RR pi stacking and
features a quantum chemical calculation of the interaction.
