Abstract
Current theories successfully predict the equilibrium structure of many simple liquids near their triple point from the repulsive molecular forces alone. We present a simple model substance whose liquid structure cannot be predicted adequately with only the repulsions. Furthermore, the model’s crystal structure changes drastically upon the removal of the attractions. This failure for our model to conform to the accepted picture of simple liquids gives us the opportunity to sharpen the boundary between substances which, respectively, may and may not be expected to so conform. We conclude that the structure of the corresponding solid deserves more weight than is conventionally given by modern theories of liquids.
