14:00 - 16:00Down to atto-world to observe motion in the frozen molecular frame     

In this contribution, ultrafast spectroscopy will be introduced as a probe of chemical reaction dynamics. One of the main goals of this field is to replace purely mechanistic “arrows” in organic chemistry by in-depth understanding of the reaction pathways. In fact, ultrafast spectroscopy can in principle do even more – short laser pulses can be used to shape the outcome of chemical reactions by acting like a light catalyst.

Ultrafast spectroscopy has been from the very beginning tightly connected with the development of laser sources capable of generating short laser pulses. Everything started in 1950 by the invention of flash photolysis which allowed the detection of intermediate radicals during chemical reactions. The field advanced in the 1980s by the discovery of the colliding-pulse mode-locked dye laser, which could produce laser pulses as short as 30 fs. A major breakthrough came in 1990 with the invention of the self mode-locking in Ti:sapphire-based lasers.…
