Abstract

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.
