Tapscott and Douglas Mather proposed that incorporation of certain molecular features in to fluoro carbons can decrease the tropospheric lifetime, providing commercially applicable chemicals with low global warming and stratospheric ozone impacts [52]. Drage et al. measured the high resolution (0.03/cm) absolute infrared photo absorption cross-sections of bromotrifluoromethane (CF3Br) and tetrafluoroethylene (C2F4) using Fourier – transformed infrared (FTIR) spectroscopy at temperatures between 213 and 296 K and the measured cross-sections were subsequently used to estimate the radiative forcings and the GWPs of these two species [53]. Tat- suru Shirafugi et al. prepared low dielectric constant fluorinated amorphous carbon films from the low GWP gas of C5F8 by a capaci- tively coupled plasma enhanced chemical vapor deposition method
