, while O2 channels are kinetically inaccessible. Classical dynamics reveal rapid nucleation and stable clustering, with water molecules enhancing cohesion through cooperative hydrogen bonding. These results identify cycloadditions with carbonyls as competitive tropospheric sinks for Criegee intermediates and emphasize how emissions from Southern Hemisphere forests may contribute to secondary organic aerosol growth and cloud condensation nuclei formation, with implications for regional climate models.
