摘要：

The integrated absorption coefficients of CF3OCF2H, CF1HOCF2H, CH3OCF2CF2H, CH3OCF2CFClH, CH3CH2OCF2CF2H, CF3CH2OCF2CF2H and CH2 = CHCH2OCF2CF2H have been measured at 298 K for use in calculations of their global warming potentials. The results for the ethers were compared to the integrated absorption coefficients of a standard compound, CCl3F. To assess the potential impact of the ethers on terrestrial infrared radiation, the absorption coefficients were both weighted by the Plank function and also used in the simple method of estimating the instantaneous radiative forcing given in Pinnock et al.
