Abstract
<jats:p>&amp;lt;p&amp;gt;&amp;lt;strong&amp;gt;Abstract.&amp;lt;/strong&amp;gt; Secondary organic aerosols (SOA) account for a large fraction of submicron particles in the atmosphere. SOA can occur in amorphous solid or semi-solid phase states depending on chemical composition, relative humidity (RH), and temperature. The phase transition between amorphous solid and semi-solid states occurs at the glass transition temperature (&amp;lt;i&amp;gt;T&amp;lt;/i&amp;gt;&amp;lt;sub&amp;gt;g&amp;lt;/sub&amp;gt;). We have recently developed a method to estimate &amp;lt;i&amp;gt;T&amp;lt;/i&amp;gt;&amp;lt;sub&amp;gt;g&amp;lt;/sub&amp;gt; of pure compounds containing carbon...
