Life, at least as we know it, would not be possible without light. The sun is the driving force behind photosynthesis, which produces oxygen in plants, and without light there would be no oxygen and thus, no humans. Light also initiates many other chemical reactions which are vital in biology and it is also used in medicine as well as for information technology. To advance many fields, it is therefore important to understand how molecules behave in the presence of light. Since the advent of femtosecond (1 fs=10^-15 s) spectroscopy just less than two decades ago, researchers can directly observe how atoms move in the time scale of a few hundred femtoseconds, initiating chemical reactions. In our group we watch molecules dancing to light with the help of different dynamical methods. These methods allow us to follow and even control the primary steps of a chemical reaction on a computer from femtoseconds to nanoseconds. With the help of this information we contribute to the rational design of photoactive devices to be used, for example, in solar cells or for photodynamical therapy against cancer. This lecture will show the recent progress of my group in simulating chemical reactions in real time from small to large molecular systems.
