<abstract>
<p>We present vapor pressure data of the C&lt;sub&gt;2&lt;/sub&gt; to C&lt;sub&gt;5&lt;/sub&gt;
      dicarboxylic acids deduced from measured evaporation rates of
      single levitated particles as both, aqueous droplets and solid
      crystals. The data of aqueous solution particles over a wide
      concentration range allow us to directly calculate activities
      of the dicarboxylic acids and comparison of these activities
      with parameterizations reported in the literature. The data of
      the pure liquid state acids, i.e. the dicarboxylic acids in
      their supercooled melt state, exhibit no even-odd alternation
      in vapor pressure, while the acids in the solid form do. This
      observation is consistent with the known solubilities of the
      acids and our measured vapor pressures of the supercooled
      melt. Thus, the gas/particle partitioning of the different
      dicarboxylic acids in the atmosphere depends strongly on the
      physical state of the aerosol phase, the difference being
      largest for the even acids.
&lt;br&gt;&lt;br&gt;
      Our results show also that, in general, measurements of vapor
      pressures of solid dicarboxylic acids may be compromised by
      the presence of polymorphic forms,
      crystalline structures with a high defect number, and/or
      solvent inclusions in the solid material, yielding a higher
      vapor pressure than the one of the thermodynamically stable
      crystalline form at the same temperature.</p>
