      abstract     = {We studied the noise spectra of molecule-free and
                      molecule-containing mechanically controllable break
                      junctions. Both types of junctions revealed typical 1/f
                      noise characteristics at different distances between the
                      contacts with square dependence of current noise power
                      spectral density on current. Additional Lorentzian-shape
                      (1/f(2)) noise components were recorded only when
                      nanoelectrodes were bridged by individual 1,4-benzenediamine
                      molecule. The characteristic frequency of the revealed
                      1/f(2) noise related to a single bridging molecule
                      correlates with the lock-in current amplitudes. The recorded
                      behavior of Lorentzian-shape noise component as a function
                      of current is interpreted as the manifestation of a dynamic
                      reconfiguration of molecular coupling to the metal
                      electrodes. We propose a phenomenological model that
                      correlates the charge transport via a single molecule with
                      the reconfiguration of its coupling to the metal electrodes.
                      Experimentally obtained results are in good agreement with
                      theoretical ones and indicate that coupling between the
                      molecule metal electrodes is important aspect that should be
                      taken into account. (C) 2012 American Institute of Physics.
