<abstract>
<p>The formation of organic nitrates and secondary organic
      aerosol (SOA) were monitored during the NO&lt;sub&gt;3&lt;/sub&gt; + limonene
      reaction in the atmosphere simulation chamber SAPHIR at
      Research Center JÃ¼lich.  The 24-h run began in a purged,
      dry, particle-free chamber and comprised two injections of
      limonene and oxidants, such that the first experiment measured
      SOA yield in the absence of seed aerosol, and the second
      experiment yields in the presence of 10 Î¼g m&lt;sup&gt;âˆ’3&lt;/sup&gt;
      seed organic aerosol.  After each injection, two separate
      increases in aerosol mass were observed, corresponding to
      sequential oxidation of the two limonene double bonds.
      Analysis of the measured NO&lt;sub&gt;3&lt;/sub&gt;, limonene, product
      nitrate concentrations, and aerosol properties provides
      mechanistic insight and constrains rate constants, branching
      ratios and vapor pressures of the products.  The organic
      nitrate yield from NO&lt;sub&gt;3&lt;/sub&gt; + limonene is
      â‰ˆ30%. The SOA mass yield was observed to be 25â€“40%.
      The first injection is reproduced by a kinetic model.  PMF
      analysis of the aerosol composition suggests that much of the
      aerosol mass results from combined oxidation by both
      O&lt;sub&gt;3&lt;/sub&gt; and NO&lt;sub&gt;3&lt;/sub&gt;, e.g., oxidation of
      NO&lt;sub&gt;3&lt;/sub&gt; + limonene products by O&lt;sub&gt;3&lt;/sub&gt;.  Further, later
      aerosol nitrate mass seems to derive from heterogeneous uptake
      of NO&lt;sub&gt;3&lt;/sub&gt; onto unreacted aerosol alkene.</p>
