We first assessed how the modified parameterization impacted the models' properties. The revised force constants reduced high vibrational frequencies within the fragment molecules, as evidenced by the power spectra, which led to higher simulation stability. Consequently, the time step could be extended to 20 fs, enhancing the performance. Importantly, the reparametrization did not significantly increase the deviation between the bonded distributions of atomistic and coarse-grained fragments, as measured by the TMS.
