  We report on the first Raman data of Cu substituted
La(1-y)Sr(y)Mn(1-x)Cu(x)O3 (0 < x < 0.10 and 0.17 < y < 0.3, accordingly in
order to have the same Mn(4+)/[Mn(4+)+Mn(3+)] ratio), collected in the
frequency range 100-900 cm-1 and at room temperature, with parallel and crossed
polarizations of the incident and scattered light. Spectra were fitted with a
Drude-Lorentz model, and peaks at 190-220 and 430 cm-1, together with two broad
structures centered at near 500 and 670 cm-1, have been found. We also have
observed that the A1g mode is substantially shifted with increasing Cu
substitution. The A1g phonon shift is a linear function of the tolerance factor
t and the rhombohedral angle, thus following the structural changes of the MnO6
octahedra in the system.
