The site-dependent replacement of 16O with 18O in YBa2Cu3O7 has been identified by Raman scattering measurements of different vibrational modes in the CuO2 and BaO planes. The shift in Raman frequency due to isotope replacement for different modes in inequivalent oxygen sites shows different temperature dependences. The activation energy for 18O replacement in the BaO plane is lower than that in the CuO2 plane.
