heal.abstract	We report novel Raman measurements made on Pr0.5Ca0.5MnO3 thin films grown on SrTiO3 and LaAlO3 (PCMO/STO and PCMO/LAO, respectively). The measurements were performed for a temperature range 78 K < T < 295 K. Different scattering polarizations (xx, xz, x′x′, and x′z′) have been selected for certain temperatures in order to make the assignment of the modes, appearing in the Raman spectra. X-ray diffraction measurements have shown that the PCMO/STO film is [010]-oriented and the PCMO/LAO film is [101]-oriented due to the lattice mismatch. Close to the transition temperature to the charge ordered state, TCO, an increase in relative intensities of the high energy modes has been observed with decreasing temperature.	en
