Abstract: Liquid-vapor coexistence curves and critical parameters for hard-core 1:1 electrolyte models with diameter ratios l s 2 s 1 1 to 5.7 have been studied by fine-discretization Monte Carlo methods. Normalizing via the length scale s 6 1 2 s 1 1s 2 , relevant for the low densities in question, both T c ( k B T c s 6 q 2 ) and r c ( r c s 3 6 ) decrease rapidly (from 0.05 to 0.03 and 0.08 to 0.04, respectively) as l increases. These trends, which unequivocally contradict current theories, are closely mirrored by results for tightly tethered dipolar dimers (with T c lower by 0% 11% and r c greater by 37% 12% )
