We calculate the electron-phonon coupling for La 2 CuO 4 , and show that it is strong enough to lead to small polarons, as seen experimentally. The calculated line shapes are in reasonable agreement with experiment. Deriving sum rules, we show that for a weakly doped system, the Coulomb interaction
