Raman and infrared spectroscopic study of C60F18, C60F36 and C60F48.

Vibrational spectroscopies have been employed to study the fluorofullerenes of formula C60F18, C60F36, and C60F48. For the first time, the Raman spectra of C60F18, C60F36, and C60F48 as well as infrared (IR) spectra of their gaseous molecules isolated in cryogenic matrices have been obtained. The results were discussed and compared with the infrared spectra of the corresponding solids. In the case of C60F18, experimental data were supported by theoretical calculations.
