ozonolysis experiment. Since propene is not an organic aerosol precursor, the compaction
cannot be explained by an earlier hypothesis attributing the compaction to the capillary
forces of condensed organic matter in the small angle cavities of the aggregates [Saathoff,
Naumann et al.(2003). Coating of soot and (NH4) 2 SO4 particles by ozonolysis products of
alpha-pinene. Journal of Aerosol Science, 34, 1297–1321]. Several species among the gas …
