✦ Synopsis

The infrared spectrum of HCFC-142b, CH 3 CF 2 Cl, has been recorded at high and low resolution using a supersonic jet-FTIR spectrometer system. Molecular parameters for a number of vibrational states have been obtained from rovibrational analyses of the C-type bands n 14 (1192 cm 01 ) and n 15 (967 cm 01 ), the A-type band n 7 (905 cm 01 ), and the B-type bands n 5 (1234 cm 01 ) and n 7 / n 11 (1215 cm 01 ). A rotational temperature of ca. 50 K in the jet expansion has been estimated from a comparison of the experimental spectrum with band simulations calculated using the resultant molecular constants.
