“…This model appears to be rather crude, and it is not supported by the results of moleculardynamics simulations of DNA 18,19 or even by the more extended electrostatic models using a heterogeneous dielectric medium. 2,[6][7][8] As expected, the calculation carried out using 0 = 1 = 2 = 1.0 leads to quite delocalized hole states in ͑GC͒ n . For instance, we obtain that in ͑GC͒ 5 q 0 = 0.476, q ±1 = 0.251, q ±2 = 0.011.…”
