Infrared absorption spectra of Bi-system high zero resistance temperature (Tc) superconductors were measured. The relation between Cu-O bond stretching vibration in CuO2 plane and superconducting properties of Bi-system high Tc superconductors were analysed and discussed. The result of analysis indicated that the change of absorption peak strength of Cu-O bond stretching vibration was similar to the change of Tc. The reason was related to the coupling between the phonon and free carrier. And according to the theory of molecule vibration, the frequencies of Cu-O bond stretching vibration in CuO2 plane were calculated on the base of simplified model.
