    • Ronald Breslow (private communication) has pointed out that another way to ensure that the rings are in fact coplanar is to consider instead dihydrophenanthrene. The geometry dependence of the current has been studied by Ghosh et al. (ref 2); cf. also Troisi, A.; Ratner, M. A.; Nitzan, A. J. Chem. Phys. 2003, 118, 6072

    • This was seen clearly in figures showing changes in the spatial distribution of total charge in response to changes in gate voltage. These figures are not reproduced here for lack of space.

    • note
    • By state density we mean the difference in density of energy eigenstates between two systems: the electrodes together with the molecule, and the same electrodes (with the same spacing) without the molecule. The eigenstates are those of the single-particle equations of the density functional formalism.
