Chemical reactions are determined at their most fundamental level by their respective electronic structure and dynamics. Steered by a stimulus such as light irradiation, electrons rearrange themselves in liquids or solids. This process takes only a few hundred attoseconds, whereby one attosecond is the billionth part of a billionth of a second. Electrons are sensitive to external fields, so researchers can easily control them by irradiating the electrons with light pulses. As soon as they thus t...
