摘要：

Infrared absorbance cross sections and integrated band strengths for HCFC-142b a (1-chloro-1,1-difluoroethane, CH3CCIF2) vapour have been determined at six temperatures (203, 213, 233, 253, 273 and 294 K) for the region 600-1500 cm(-1) by Fourier transform infrared spectroscopy. Air-broadened spectra of HCFC 142b vapour have been recorded at 203, 253 and 294 K using mixtures containing 5, 20 and 100 kPa dry air. Spectroscopic resolution was 0.03 cm(-1), with additional high resolution (0.002 cm (-1)) measurements of the pure vapour at 203 and 294 K.
