This will make it possible to directly control chemical reactions and biological processes and obtain a desired result literally at the touch of a button. Using “attophysics”- the study of events with attosecond time resolution (10^-18 of a second), the researchers are trying to track the ultrafast movement of electrons in molecules, or more precisely the restructuring of their electron shells. These processes are the key to understanding chemical and biochemical reactions, as it is the “redistribution” of electrons that is involved in the formation of new chemical bonds...
