Slow Vibrations in Transport through Molecules
  We show how one can measure the signal from slow jumps of a single molecule between metastable positions using a setup where the molecule is fixed to one lead, and one of the coupling strengths is controlled externally. Such a measurement yields information about slow processes deforming the molecule in times much longer than the characteristic time scales for the electron transport process.
