The table presents all significant parameter results of the fitting of the EXAFS Au K-edge spectra of AuNR-HQ and AuNR-AA. Here R2 is the square residual factor, N the multiplicity factor, R the interatomic distance and σ2 the Debye–Waller factor. The symbol * highlights the constrained values. The passive electron reduction factor S02 = 0.9 and the energy scale shift ΔE0 = 6.85 eV were kept fixed.
