The experimental observation of phonon renormalization in high-T{sub c} superconductors gives clear evidence for the action of electron-phonon coupling. But in spite of the estimated coupling strength {lambda} {approximately} 1-3, these effects do not allow for a unique identification of the coupling mechanism. This situation is contrasted with that for the low-T{sub c} superconductors where tunneling spectroscopy provides a hard proof for electron pairing via phonons.
