EDR functions presented in section 4.2.3 have been sampled at a step size of 0.2 Bohr over the entire carbon chains, and its values have been multiplied by the electron density at the same point in space and summed to a single number for a given delocalization length u. In the EDR approach, this procedure must be consistent with the number of electrons in the system. For more information, please refer to the Appendix A.2.3. All the DI values have been obtained using Multiwfn software. 167
