The behavior of electrons in liquids is crucial to understanding many chemical processes that occur in our world. Using advanced lasers that operate at the attosecond, a team of international researchers has revealed further insights into how electrons behave in liquids.
The behavior of electrons in liquids plays a big role in many chemical processes that are important for living things and the world in general. For example, slow electrons in liquid have the capacity to cause disruptions in the DNA strand.
An international team of researchers has now demonstrated that it is possible to probe electron dynamics in liquids using intense laser fields and to retrieve the electron's mean free path -- the average distance an electron can travel before colliding with another particle. The research team, which also included researchers from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg and ETH Zurich, reported on the unique behavior of liquids when irradiated by intense lasers. Until now, almost nothing is known about these light-induced processes in liquids, which surround us everywhere and are present in every chemical reaction.
"Measuring the effective mean free path of the electrons is very challenging in the low kinetic energy region, as was done in this study, added Yin."Ultimately, our collaborative effort establishes HHG as a new spectroscopical tool to study liquids and is therefore an important stepping stone in the quest to understand the dynamics of electrons in liquids.
