Abstract

The effect of high pressure (up to 10 GPa) on the phonon modes of azafullerene (C59N)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 ω(3) mode and the Hg(1) squashing mode frequencies, exhibit reversible changes in the pressure region (5.0 ± 0.5) GPa. In addition, the Ag(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 (C59N)2 due to the existence of the intradimer C-C bridge obtained by other techniques.
