The Raman spectra of the solid C 60 at 284～10 K were measured, and the intensity temperature curves were illustrated. For all these curves, the mutation appeared at the first order phase transition temperature 250 K. The intensity and its variation of A g mode were higher than that of H g. For the curves of 1470 and 498 cm -1 , its fluctuatory tendencies were opposite, one was rising just other was decreasing. It is considered that the radial vibrations were the major motions for inner mode vibrations of molecule, and there were some competitive function between two A g modes. The nonlinear optical effect near phase transition temperature would br more obvious.
