A comparison between the GPR distribution and FFMD model predictions shows that the models significantly deviate from the experiment at Q < 2.5 Å-1 . Furthermore, the difference between the CHARMM36 and prosECCo75 FFMD data becomes particularly pronounced in this low-Q region (see Fig. ), with the later model agreeing much better with the experiment. This result sug-gests that charge scaling significantly improves the description of long range density correlations in TMA-pyridine systems. Lastly, the GPR predicted noise on the experimental data (σ noise ∼ 0.037)
