Sr2CuO2Cl2. Signifies an almost suitable scenario of the two-D antiferromagnetic CuO2-airplane and thus is of specific curiosity in the context in the origins of higher TC superconductivity. We use The one-site impurity Anderson product with 5 Cu 3d orbitals and O 2p valence bands specified by the irreducible representations with https://okada4dsg.com/
