IR band intensities have been measured for the species: CF 4 , C 2 F 6 , C 3 F 8 , C 4 F 10 , C 5 F 12 , and C 6 F 14 via Fourier transform spectroscopy and compared to previous literature values if available. Relative radiative forcing calculations have been performed using these data in order to determine the global warming potential of the particular species. The relative forcing (compared to CFC11, per volume) increases with molecular weight in the above series from 0.47 to 2.1, the GWP for a time horizon of 100 yrs from 1.1 to 4.7. This corresponds to a GWP on CO 2 basis per mass of about 5000.
