N2 - The effect of high pressure (up to 11 GPa) on the phonon modes of o-CsC60 polymer has been studied by means of Raman spectroscopy. The pressure dependence of all the observed phonon frequencies exhibits reversible changes in the pressure region 4.3 ± 0.5 GPa. The width of the Hg(8) mode increases almost linearly with increasing pressure up to approx. 4.3 GPa, above which it seems to remain constant. All the above changes may be related to the metal-insulator transition observed below 50 K for the material under investigation and/or with the structural changes, induced by pressure and observed also by X-ray diffraction measurements.
