Abstract

The target is the investigation, with extreme temporal resolution, of molecular processes initiated by the interaction of ionizing radiation with biologically relevant molecules. The main objective is to identify and control at molecular level the early steps of light-driven processes of primary importance in photochemistry and photobiology, which typically evolve on timescales ranging from the attosecond domain of purely electron dynamics, to the hundreds of femtosecond domain of nuclear dynamics. The experimental strategy is based on the combination of advanced time-resolved techniques, characterized by extreme temporal resolution (from femtoseconds to hundreds of attoseconds), with synchrotron-based spectroscopic techniques to unravel the molecular mechanisms leading to photo-protection or damage of bio-relevant molecules. Advanced numerical modelling, based on a novel and unique theoretical approach which takes into account the atomistic details of the molecular structure, the action of the extreme-ultraviolet and ultrashort excitation, electron correlation effects and the coupling between electronic and nuclear degrees of freedom, will support and guide the experiments.
