Single molecular transport

Section 5 is on one particular molecule, p-benzene dithiol. This is one of the most commonly studied molecules in molecular electronic transport junctions [7] (although it is also one of the most problematic). Section 6 discusses a separate measurement, inelastic electron tunneling spectroscopy [8, 9] (IETS). This can be quite accurate because it can be done on single molecules at low temperatures. It occurs because of small perturbations on the coherent transport, but it can be very indicative of such issues as the geometrical arrangement in the molecular transport junction, and pathways for electron transport through the molecular structure. 

The field sometimes called molecular electronics actually should extend well beyond simple measurement of current/voltage characteristics of single molecules. The latter topic, single molecule transport, has comprised by far the dominant reported molecular electronics measurement and modeling, and, as has been discussed above, the community is reaching some agreement in this area.
