The Raman spectra of Nd2Cu04_x single crystals have been measured. The lines in the spectra are classified on the basis of a symmetry analysis of the phonon modes at the Γ point in the Brillouin zone, a comparison of the masses of the vibrating ions, and a comparison with the vibrations in high-Tc superconductors which have been studied previously. A two-magnon scattering light is observed.
