Sr2CuO2Cl2. signifies a virtually best situation of a 2-D antiferromagnetic CuO2-aircraft and therefore is of certain interest within the context of your origins of superior TC superconductivity. We've measured experimentally and analyzed theoretically the Ti 2p X-ray photoemission spectra (XPS) plus the resonant improvement of valence photoemissionat the Ti 2p https://okada4dsg.com/
