13 C solid-state NMR measurements are reported for several polyaniline-HCl samples and the insulator/metal transition is observed. By means of the renormalization approach, we also present numerical calculations of coherent conductance and density of states for different configurations of long linear chains of emeraldine salt. We discus the roll of decoherence as the trigger for the observed metallic properties in these polymers.
