Infrared band strengths and their temperature dependence of the hydrohalocarbons HFC-134a, HFC-152a, HCFC-22, HCFC-123 and HCFC-142bFunded under: FP1-ENVPROT 4C
The absolute strength of the IR absorption bands of five halocarbons, proposed as substitutes of chlorofluorocarbons, have been measured at 293, 273 and 233 K in the wavelength region 600-1500/cm. The band strengths were derived from measurements performed using an FT-IR spectrometer operating at 0.1/cm instrumental resolution. The values obtained are compared to those from previous studies. Only a slight temperature dependence was observed, indicating a small increase of the band strengths at decreasing temperatures.
