Figure 4: The total (measured x-ray) differential pair distribution function for the 1:1 LP:HPCM-E3 mixture (top, left) and 1:1 LP:HPCM-P mixture (top, right) each broken down into three components.

Pure polymer, LP intramolecular component and LP intermolecular PDF (obtained by subtracting the polymer and LP intra from the total). The LP intermolecular PDF isolates out the intermolecular drug-drug and drug-polymer interactions present.
