Short summary
Halocarbon gases (used e.g. in air conditioning) contribute to climate change. Their inclusion in international legislation needs emission metrics that characterise their climate importance; this requires good knowledge of how well they absorb infrared (IR) radiation. Little previous work has quantified absorption at long IR wavelengths. We report new calculations, previously validated against measurements, that improve understanding for 30 gases and allow refined estimates of emission metrics.
