    • The rotational barrier about the single bond in a conjugated diene is ∼6 kcal/mol, where the local minima of the s-cis conformer lies ∼2 kcal/mol higher in energy (see, ()). Time-dependent DFT calculations on a D3 (all s-trans) estimates the rotation about the a single bond at 4 kcal/mol. Calculations suggest that orbitals energies of these conformers are similar and also that molecular length is does not change significantly before and after rotation The s-trans/s-cis conformers are not expected to account for the dramatic difference between the high- and low-conductance states in our break junction measurements but may contribute to peak broadening

    • 2. This model offers the empty orbital space (Lewis acidity) into which the S lone pair can delocalize to form the donor-acceptor bond that initiates the molecular-bridge-forming process.
