Information on origin of the data:

Normalized Cu K-edge XANES of a Cu-CHA sample (Si/Al = 5, Cu/Al = 0.3), collected during heating from RT to 350 °C under a He flow. In situ data were collected at the BM23 beamline of the European Synchrotron Radiation Facility (ESRF, Grenoble, France) in a  Microtomo reactor cell

Cu L3-edge TEY NEXAFS spectra of of a Cu-CHA sample (Si/Al = 5, Cu/Al = 0.3), collected during heating from RT to 350 °C under a He flow. In situ data were collected at the APE-HE beamline of Elettra Sincrotrone Trieste (Basovizza, Italy) in a dedicated ambient pressure cell.
