The table presents all significant parameter results of the fitting of the EXAFS Ag K-edge spectra of AuNR-HQ and AuNR-AA, where N is 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 = 0.85 and the energy scale shift ΔE₀ = 0.8 eV were kept fixed.
