Description
Pump-Probe experiments have become routinely employed tools in the field of spectroscopy, because they give the possibility to reach the time-resolution necessary to unravel dynamics of chemical reactions and physical processes. The goal of my PhD project will be that of investigating such kind of phenomena taking advantage of the radiation provided by FERMI, the free electron laser located in Trieste.Thanks to the seeding scheme, FERMI extreme ultra-violet source (EUV) possess the unique capabilities of being finely tuneable, and most importantly, to be jitter-free. The latter feature is of paramount importance to perform time resolved experiments. The combination of these peculiar characteristics allow to perform time-resolved investigations with a chemical selectivity.I will present some preliminary results from an experiment conducted on the thermite reaction aiming at the real-time observation of the redox reaction that transforms Al and Fe2O3 into Al2O3 and Fe. I will then present another possible study on which I might work, which involves the investigation of the influence of selective coherent acoustical phononic excitation on photoactivated charge-transfer processes.
