Program | It is well known that light interacts differently with small particles compared with bulk materials or gas phase molecules, producing spectral signatures that strongly depend on particle properties, such as size, shape, or architecture. Even molecular aggregates that are held together by weak intermolecular interactions can exhibit such characteristic spectral signatures. This talk provides an overview of our research in this field. I will present our latest results on the behavior of slow electrons in molecular aggregates and nanoscale aerosol particles obtained from angle-resolved photoelectron spectroscopy. In the second part, I will introduce a new experimental setup that combines Laval expansions with mass spectrometric detection, which is intended for the study of fundamental aspects of gas phase nucleation. Finally, I will briefly discuss our latest attempts to perform spectroscopic studies on single submicron-sized aerosol droplets in optical traps. | |
