Notably, other potential patterns of time-dependent structural evolution exhibited a similar trend in SAXS S(q), such as clusters with temporally changing radii of gyration. However, MPM computations demonstrated that those alternative scenarios displayed far-field spectral shifts in the opposite direction of the experimental data. Thus, the consideration of SAXS and UV-Vis-NIR spectroscopic characterization together with Brownian dynamics modeling and MPM proved powerful for discerning between competing microscopic structural trends that would be impossible to decipher with SAXS experiments and Brownian dynamics simulations alone.
