Radial distribution function (rdf) is another important analysis as it illustrates the intermolecular interactions of the models. Therefore, the rdf of all atoms within one polymer chain with respect to all other surrounding molecules (i.e., polymer chains in case of "melt" and repeat units in case of "soup") are shown in Figure (right panel). As shown, the most shortrange inter-chain interactions have been captured by the "soup" method. However, the longrange orders cannot be reproduced by the "soup" method. This is, however, somehow expected due to the removal of the natural confinement imposed by the inter-repeat unit covalent bonds in surrounding polymer chains in case of "soup" models. Nevertheless, as we will see in the next section, the difference in rdf between "soup" and "melt" snapshots does not necessarily translate into a difference in the main quantities of merit (DOS and LL).
