study of aerosol particles with sizes in the submicron range is an
interdisciplinary endeavour at the junction of atmospheric chemistry,
astrophysics, and the nanosciences. The role of aerosols in atmospheric
processes, as industrial pollutants, in interstellar chemistry, and as drug
delivery systems has become an increasingly important issue in recent years. To
understand the impact of aerosols it is crucial to study the processes by which
they are formed, their physical properties, and their chemical composition and
reactivity. The present
contribution focuses on the influence of intrinsic particle properties, such as
shape, size or architecture, on the infrared optical properties of aerosol
particles. Intrinsic particle properties manifest themselves in mid-infrared
extinction spectra by modifying the structure of vibrational bands. We
ultimately aim at unravelling the microscopic origin of the characteristic
patterns found in the spectra of these weakly bound molecular aggregates. To
this end, we compare our experimental results with model calculations which
combine vibrational quantum dynamics with molecular dynamics simulations.</span></font></span><span style="font-size:14.0pt;font-family:Arial;color:navy"><o:p></o:p></span></p><p class="MsoNormal" align="center" style="text-align:center"><span style="font-size:16.0pt"> <o:p></o:p></span></p><p class="MsoNormal" align="center" style="text-align:center"><font class="Apple-style-span" size="4"><span class="Apple-style-span" style="font-size: 14px;"> <o:p></o:p></span></font></p><p class="MsoNormal" align="center" style="text-align:center"><font class="Apple-style-span" size="4"><span class="Apple-style-span" style="font-size: 14px;">Grier Room, MIT Bldg 34-401<o:p></o:p></span></font></p><p class="MsoNormal" align="center" style="text-align:center"><font class="Apple-style-span" size="4"><span class="Apple-style-span" style="font-size: 14px;">Refreshments served after the lecture</span></font><o:p></o:p></p>
