✦ Synopsis

The effect of high pressure (up to 10 GPa) on the phonon modes of azafullerene (C 59 N) 2 has been studied by means of Raman spectroscopy. The dimeric character of this fullerene derivative is manifested in its Raman spectrum. The pressure dependence of the w(3) mode and the H g (1) squashing mode frequencies exhibit reversible changes in the pressure region (5.0 AE 0.5) GPa. In addition, the A g (1) breathing mode shows two clear reversible changes in its pressure coefficient at %3.0 and %5.5 GPa. These results are consistent with the structural modifications of (C 59 N) 2 due to the existence of the intradimer C±C bridge obtained by other techniques.
