We report on an infrared study of the resonance interaction between phonons and electronic excitations in an YBa2Cu307 single crystal. Our results show that two transverse axial phonon modes (to= 300 cm-t and to-~ 550 cm -1 ) are strongly coupled to the c-polarized electronic continuum resulting in
