We present evidence via molecular simulation that the supercooled fluid states of SPC/E water as well "repulsive" and "attractive" a recently introduced model for colloids with short-ranged attractions are characterized by same functional relationship between self-diffusivity pair correlation function. discuss how this simple connects to an earlier finding temperature dependency fluid's single-particle dynamics tracks its excess entropy (relative ideal gas). The generality observed structure−property is supported ability successfully describe nontrivial behaviors these very different types systems.
