Cu (CO3) 2, and CuSO4 where Cu is present in oxidation state of 2+, using the energy
dispersive EXAFS beamline at INDUS-2 Synchrotron radiation source at RRCAT, Indore.
Energy shifts of∼ 4–7eV were observed for Cu K X-ray absorption edge in the above
compounds compared to its value in elemental copper. The difference in the Cu K edge
energy shifts in the different compounds having same oxidation state of Cu shows the effect …
