Sr2CuO2Cl2. Represents an almost ideal scenario of a 2-D antiferromagnetic CuO2-plane and thus is of unique desire in the context on the origins of superior TC superconductivity. We now have measured experimentally and analyzed theoretically the Ti 2p X-ray photoemission spectra (XPS) and also the resonant improvement of valence photoemissionat https://okada4dsg.com/
