Furthermore, for the oxyacid-assisted oxide nucleation, the collision of (IP) 1 (IsA) 1 and similar oxide + oxyacid clusters was allowed to grow out of the system, even if they only collided with another oxyacid. The resulting cluster is thus effectively only a tetramer, and will lead to an overestimation of the nucleation potential. However, this is unlikely due to the high stability of these clusters at this level of theory combined with the observation that the stability of iodine oxide clusters is still underestimated compared to iodine oxyacids, even at this level of theory.
