Two frames of a STM movie show the Rh2dimer flipping between two symmetrically equivalent configurations between the surface Fe rows. The yellow arrows each indicate an immobile 2-fold coordinated Rh1atom, which is used as a reference. The Rh2dimers are marked by cyan arrows. The dashed white lines indicate the same position in the two frames of the STM movie.
