The molecular dynamics of an electron‐induced reaction in a self‐assembled molecular chain of four dimethyldisulfide molecules on Au(111) are studied (see figure, SS bonds highlighted). Charge delocalization weakens all the SS bonds causing a concurrent reaction along the entire chain (middle). All the original SS bonds are broken and new SS bonds form giving three altered SS bonds and two chemisorbed thiyl radicals (bottom).
