چکیده انگلیسی
CF3I is being considered as a replacement for some of the global warming gases currently used in the plasma industry, however before this compound can be put into wide-scale use the possible implications upon the atmosphere must be carefully considered. Calculations of global warming potentials of compounds require detailed information about the infrared absorption properties of a compound. High resolution Fourier transform infrared spectroscopy has been applied to CF3I to measure absolute infrared photo absorption cross-sections. These have been measured in the ranges (400-1400)Â cmâ1 and (1900-2500)Â cmâ1 at a resolution of 0.003Â cmâ1 for temperatures of 208.0, 251.6, 272.9 and 299.4Â K over a range of pressures. Eight absorption features were observed across the measured range some of which lie within the atmospheric IR (800-1300Â cmâ1) window and hence may play a role in global warming.
