Sr2CuO2Cl2. Signifies a nearly perfect case of a two-D antiferromagnetic CuO2-aircraft and therefore is of specific desire during the context on the origins of substantial TC superconductivity. We have now calculated experimentally and analyzed theoretically the Ti 2p X-ray photoemission spectra (XPS) along with the resonant enhancement of valence photoemissionat https://okada4dsg.com/
