We investigate the three-band extended Hubbard model for the CuO 2 planes of high-temperature superconductors. We consider the limit of U = I on Cu atoms and we include the nearest-neighbor Coulomb repulsion between holes on 2p x,y orbitals of oxygen and holes on 3d x 2 Γy 2 or 3d 3z 2 Γr 2 orbitals

Sonic velocity measurements have been used for some time to determine the specific heats of gases at low frequencies following the suggestion of Einstein (1) 2 that the reaction rates of reactive gas mixtures could be found from similar measurements. However, the equation for sonic velocity expresse
