We identify the lowest local energy state in the CuO2 plane of cuprate superconductors, the vibration that does not involve distortions of constituent units of the plane, the Rigid Unit Mode (RUM). On lowering the temperature, correlated atomic motion in the plane is related to the RUM vibration. We discuss the relevance of this vibration for superconductivity, including electron-phonon coupling, d-wave symmetry of the order parameter, structural state of the CuO2 plane and spatial variations of the electronic structure.
