Description
FERMI is a world unique free electron laser, that thanks to the seeding scheme can deliver coherent pulses up to the carbon K edge, with an exquisite polarization, photon energy and timing control. These properties, corroborated by multi-colors emission schemes permit to perform non-linear optics time-resolved experiments, with the long dreamed achievement of the chemical sensitivity. In this talk, I will present recent non-linear optics experiments conducted at the EIS-TIMER and EIS-TIMEX beamlines aimed at resolving with chemical sensitivity different dynamics in prototypical systems. In particular, I will focus on the vibrational dynamic of Ibuprofen and Hydroxychloroquine projected on their atomic constituents and a proof of principle study performed on the thermite compound designed to visualize the temporal evolution of the redox reaction happening between iron oxide and aluminum. These preliminary studies, combined with the transient grating capabilities of the EIS-TIMER beamline, open the way to the design of more complex experiments aimed at elucidating the role of coherent vibrations on the charge transfer mechanisms.
