Towards Unravelling Solvation Dynamics: From Isolated Molecules to Micro-Hydrated Environments — •Deepak K. Pandey1, Liliana M. Ramos Moreno1, Claus-Peter Schulz2, and Jochen Mikosch1 — 1Institut für Physik, Universität Kassel, Kassel, Germany — 2Max Born Institute (MBI), Berlin, Germany
Exploring the behavior of micro-solvated molecules is vital for bridging our understanding of isolated molecules in bulk-liquid environments. Through the gradual addition of water molecules one at a time, our research explores the effects of solvation on neutral molecules. We employ Photoelectron Photoion Coincidence (PEPICO) spectroscopy to investigate both the static and dynamic effects of solvation. Our experimental setup at the University of Kassel employs a water cluster technique to systematically investigate how micro-hydration affects molecular behavior. Using ultrafast pump-probe experiments, this technique enables us to investigate how solvation affects photochemical processes such as photodissociation and photo-induced isomerization. In the past year, we have achieved coincidence measurements with our PEPICO spectrometer, making significant progress in characterizing our water cluster source. With the goal to gain greater insight into the dynamics of micro-hydrated chiral molecules, we intend to include the time-resolved Photoelectron Circular Dichroism (PECD) investigations in the future. Our poster emphasizes on the experimental methodology, analysis of the water cluster source and spectrometer, and progress made in experimental techniques for investigating the molecular dynamics of chemical processes.
