The High-Resolution FTIR Spectrum of Jet-Cooled CH3CF2Cl
The infrared spectrum of HCFC-142b, CH3CF2Cl, 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 nu14 (1192 cm-1) and nu15 (967 cm-1), the A-type band nu7 (905 cm-1), and the B-type bands nu5 (1234 cm-1) and nu7 + nu11 (1215 cm-1). 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.
