Sažetak
Crystal field variation induced ep coupling is evaluated for all Raman modes in YBa/sub 2/Cu/sub 3/O/sub 7/. While the symmetric modes couple to the in-plane Cu(2)-O(2, 3) charge transfer (CT) the antisymmetric 340 cm/sup -1/ mode couples to the O(2)-O(3) CT. This explains tentatively the different behavior of those modes below T/sub c/.
