    • The width of the peaks in the experimental dI/dV spectra of ≃ 0.3 V (full width at half maximum) is not limited by electronic interactions with the substrate but by the interaction of the NIR and PIR states with phonons in the insulating layer, as will be discussed elsewhere. Consequently, the shape of the peaks is not Lorentzian but Gaussian-like, and the width is independent of the NaCl layer thickness as revealed by experiment.

    • Directly above the LUMO peak there is a region of negative differential conductance. It is important to note that this is not an intrinsic electronic feature of the pentacence/NaCl/Cu system but is due to the measurement. It can simply be understood when considering that the barrier height for the electrons tunneling directly into the LUMO increases with increasing voltage.
