The Raman spectra of gutta-percha of eucommia ulmoides were measured at pressures up to 5'45GPa and room temperature.The pressure depences of conresponding atom groups on the carbon skeleton of the polymer were reported. The different pressure-induced band shift rates were analysised according to the interatomic and intermolecular interactions and geometry of the molecular chain. In the mean while
the new phenomena
such as the changes of intensity and shape of the bands and the presence of some weak bands at high pressures
were explained by effects of Fermi resonance andthe slipping of energy levels.
