This is important to note, as this means that J potential should not be used directly as a measure of the NPF rate. Studying cluster dynamics with only up to 4 molecules can lead to artificially higher values as the critical cluster size/area may not be properly covered by the cluster dynamics simulations. Kubečka et al. reported that using a simulation scheme of (acid) 0-2 (base) 0-2 instead of (acid) 0-4 (base) 0-4 for SA-multi-base clusters at low temperatures and the concentration ranges used in this work yields J potential that are between 1-2 orders of magnitude higher while the trends in formation rates remain intact.
