Sr2CuO2Cl2. Represents a nearly excellent scenario of a 2-D antiferromagnetic CuO2-plane and thus is of specific desire from the context of your origins of high TC superconductivity. We've calculated experimentally and analyzed theoretically the Ti 2p X-ray photoemission spectra (XPS) and the resonant improvement of valence photoemissionat the Ti 2p https://okada4dsg.com/
