Sr2CuO2Cl2. Signifies a nearly great situation of a two-D antiferromagnetic CuO2-plane and so is of particular interest inside the context on the origins of significant TC superconductivity. We use the single-site impurity Anderson product with 5 Cu 3d orbitals and O 2p valence bands specified through the irreducible representations of https://okada4dsg.com/
