Therefore, iodine oxyacid-amine nucleation can be a contributing factor in high amine regimes, even at high SA concentrations. .15 K at a relative humidity of 0% for the 2 cluster systems: SA nucleation given by (SA) 0-2 (base) 0-2 and IA/IsA nucleation given by (IA/IsA) 0-2 (base) 0-2 , where base a combination of AM, MA, DMA, TMA as defined in the computational details. The shaded areas in the figure corresponds to the high and low concentrations of amines given in Table In Figure , we have plotted a scan of the potential nucleation rates of "oxyacid-assisted oxide" and "pure oxyacid" nucleation. A similar scan of the SA-amine and iodine oxyacidamine pathways can be found in Figure . Figure again shows that significant concentrations of IA, ∼10 8 cm -3 , are needed to induce significant nucleation if no oxides are present.
