Abstract. The Raman spectra of insulating compound Bi2.4Sr2.6Fe2O9+δ have been measured and compared to these of the superconducting Bi2CaSr2Cu2O8+δ which has isomorphic structure. The Raman lines at 116, 157, 245, 288, 461-465 and 614 cm-1 has been assigned to definite atomic vibrations. Some earlier assignments of the Raman lines of Bi2CaSr2Cu2O8+δ have been reconsidered.
