The analyzed results of EXAFS spectra of R1 and R2. N is the coordination number, R is bond distance and σ² is Debye-Waller factor. The amplitude $\left(S_0^2\right)$ and absorption edge energy shift (ΔE₀) is fixed as 0.72 and 4.78 eV, respectively. The simulated data is compared with reported data [38, 39].
