Benzene Dithiol An Exemplary Case

There are almost 100 papers that discuss benzene dithiol s conductance. As the point about geometric distributions became well understood, it was realized that statistical analysis was extremely useful. Accordingly, electrochemical break junction techniques, both in their original form of crashed electrodes being separated to form the gap or in the newer electrochemistry form, in which a gap is created and then electrochemically modified, have proliferated. The important thing is that statistical measurements can be made [24, 90], with hundreds or thousands of data points. Not surprisingly, distributions are observed (as the earlier computations had suggested). 

Some measurements showing high conduction for benzene itself and some benzene derivatives are best explained by a geometry very different from the extended one first suggested by Reed, and serve as the basis for much calculation. In the measurements from Ruitenbeek s laboratory, the conductance is close to the atomic unit of conductance [92], The simplest way to explain this phenomenon is that the molecule is oriented perpendicular to the interelectrode coordinate, and electrodes are very near one another. So the molecule really does not assist substantially in the transport, although it can be seen in the LETS spectra.
