    • note
    • 3 solutions. The deoxyguanosine molecule is constituted of the guanine base and the deoxyribose (DNA-sugar). In the experimental structure, lipophilic alkyl chains are attached to each deoxyguanosine in order to stabilize the structure. In our model, instead, we leave out the sugar and the attached alkyl chains.

    • note
    • Guanine, being a heteronuclear and non-center symmetric molecule, has an highly asymmetric charge distribution, which induces a net dipole (|μ̄| =6.9 D), lying on the plane of the molecule. The calculation of the macroscopic polarization of a periodic crystal needs the quantum mechanical approach (King-Smith, et al. Phys. Rev. B 74, R1651 (1993)), which requires the calculation of the Berry phase or the Wannier centers for the electronic wavefunctions. In our case, we calculated the dipole moment for two finite sequences of Gs in ribbon-like configuration.
