Attosecond spectroscopy of bio-chemically relevant molecules

Our publication entitled "Attosecond chronoscopy of electron scattering in dielectric nanoparticles" has been accepted and published in La Rivista del Nuovo Cimento.

Understanding the role of the electron dynamics in the photochemistry of bio-chemically relevant molecules is key to getting access to the fundamental physical processes leading to damage, mutation and, more generally, to the alteration of the final biological functions. Sudden ionization of a large molecule has been proven to activate a sub-femtosecond charge flow throughout the molecular backbone, purely guided by electronic coherences, which could ultimately affect the photochemical response of the molecule at later times. We can follow this ultrafast charge flow in real time by exploiting the extreme time resolution provided by attosecond light sources (1 as = 10-18 s). This review provides an introduction to attosecond technology and its application to molecular spectroscopy. Both the experimental techniques and the advanced theoretical models used to capture the photo-induced electron dynamics in complex molecules are described. Advancements in this new exciting field will open new important perspectives in photochemistry and photobiology.
