Visualization of a discrete solid-state process with steady-state X-ray diffraction: observation of hopping of sulfur atoms in single crystals of realgar.
A molecular movie showing migration of a sulfur atom between molecules of realgar (alpha-As(4)S(4)) was obtained by a series of structure determinations of the dark stage of this all-solid autocatalytic reaction set.
