Raman spectra of polycrystalline YBa2Cu3Ox with various oxygen content x were recorded at 30 K. The intensity of the Cu-O stretching mode at 505 cm-1 depends on the oxygen content significantly. This peak becomes weak as the oxygen content decreases and finally disappears at x=6.05. The last result disagrees with previous Raman studies on the tetragonal phase. Other spectral changes, disappearance of the 115 cm-1 peak and shifts of some peaks, are observed at the oxygen content of ≈6.8.
