heal.abstract	Systematic Raman studies on several cuprates (YBa2Cu3Ox, YBa2Cu4O8 and Bi2Sr2CaCu2O8) have shown that at optimal doping the compounds are at the edge of lattice instability; once this level is exceeded, by means of doping or applying external hydrostatic pressure, the changes in the transition temperature are accompanied by spectral modifications. There are strong indications that the reduction in T-c is correlated with a separation into nanoscale phases, which involve the oxygen atoms of the CuO2 planes. In this work, modifications with doping in the Raman spectra of the La2-xSrxCuO4 compound are presented, which show that spin or charge ordering is coupled with lattice distortions throughout the whole doping region.	en
