The complex dielectric permittivity ε=ε′+iε″ is determined in the 0.2–2.0THz and 80–294K ranges. ε″ has a linear temperature dependence up to 200K then sharply increases. The low temperature linear dependence in ε″ suggests anharmonicity for temperatures 80K&amp;lt;t&amp;lt;180k, challenging=&quot;&quot; the=&quot;&quot; assumed=&quot;&quot; harmonicity=&quot;&quot; below=&quot;&quot; 200k.=&quot;&quot; temperature=&quot;&quot; dependence=&quot;&quot; is=&quot;&quot; consistent=&quot;&quot; with=&quot;&quot; thermally=&quot;&quot; activated=&quot;&quot; sidechain=&quot;&quot; motions=&quot;&quot; and=&quot;&quot; shows=&quot;&quot; involved=&quot;&quot; in=&quot;&quot; dynamical=&quot;&quot; transition=&quot;&quot; extend=&quot;&quot; to=&quot;&quot; subpicosecond=&quot;&quot; time=&quot;&quot; scales.&amp;lt;=&quot;&quot; div=&quot;&quot;&amp;gt;&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">4</style></issue></record></records></xml>
