      abstract     = {We introduce a method to determine the lateral diffusion
                      constants of planar organic molecules adsorbed on surfaces
                      from the temporal width tau of pulses in the tunneling
                      current measured for a stationary scanning tunneling
                      microscope tip. The method uses the molecular footprint as a
                      scale bar and evaluates tau as the first-passage time.
