Dear All

I did the RDF analysis between a set of clay surface atoms and another set of adsorbed ions. Then I got jagged RDF like following:

I read it some where that the rdf of atoms in crystal would show jagged nature because of crystalline structure. But my RDF is between ions in solution and atoms in crystal, and if do RDF between another set of clay surface atoms and the adsorbed ions, the RDF is smooth.

Does anyone have suggestion about this? Thank you.
