with D 0 = 2.81( ) and κ = 0.42 , where I m = i ν i q 2 i is the ionic strength of the electrolyte in our molecular frame. The proportionality of the interaction strength to I m is in agreement with the ionic strength dependency of the interaction energy as described by Debye and Hückel. We noticed a few exceptional cases that are, however, beyond the scope of our discussion.
