Spatial distribution functions: liquid CH3CN and CO2

Monte Carlo simulations of CH3CN and CO2 fluid phases exhibit anisotropy in the spatial distribution functions (SDFs) that is readily interpreted by mere inspection of 2D topographical plots of the SDFs: The local structure in condensed CH3CN and CO2 is dominated by dimer-like arrangements. The fact that this local structure derives from (directional) electrostatic interactions is obvious from comparisons of SDF topographies obtained from simulations with and without the partial changes associated with CH3CN and CO2.
