Composite absorption cross-sections of the hydrofluoroether HFE-347pcf2 (CAS number 406-78-0) have been determined from experimental and theoretical data. The experimental cross-sections have been used as a gauge to evaluate the accuracy of computational data obtained from different density functional theory methods. The B3LYP functional with a small 6-31G(d) basis set was found to provide the best results. A simulated spectrum was added to our experimental data to calculate the radiative efficiency and global warming potential of the molecule over the entire atmospheric spectral window. We found a radiative efficiency of 0.46 Wm⁻²ppb⁻¹ and a 100-year global warming potential of 980.
