abstract = {Recent STM molecular break-junction experiments have
revealed multiple series of peaks in the conductance
histograms of alkanedithiols. To resolve a current
controversy, we present here an in-depth study of charge
transport properties of Au|alkanedithiol|Au junctions.
Conductance histograms extracted from our STM measurements
unambiguously confirm features showing more than one set of
junction configurations. On the basis of quantum chemistry
calculations, we propose that certain combinations of
different sulfur-gold couplings and trans/gauche
conformations act as the driving agents. The present study
may have implications for experimental methodology: whenever
conductances of different junction conformations are not
statistically independent, the conductance histogram
technique can exhibit a single series only, even though a
much larger abundance of microscopic realizations exists.},
