Comparing the data extracted at 673 and 300K, the transition times diminish substantially at higher temperatures, exemplified by the characteristic timescales for s→c transition shrinking from ∼ 66 ns at 300K to ∼11 ns at 673K. Such different dynamics as a function of temperature, are even more pronounced for transitions between the inner AEs; the interior of the NP is almost static at 300K:e.g., the s→ss' (i.e., surface to subsurface) transition time drops from ∼ 10 4 ns at 300K to ∼14 ns at 673K, a diminution of three orders of magnitude. These analyses demonstrate how such a combined experimental/computational approach allows achieving a resolution of the ps scale, to reconstruct the atomic dynamics present over a real 6-second experimental time window. Such level of detail provides crucial insights, such as, e.g., how long an AE exists in realistic conditions, which is key to understanding the surface properties of these NPs.
