✦ Synopsis

The first successful detailed analysis of the high-resolution (0.005 cm-') IR spectrum of the vq band of CF&l (&= 12 16.75843( 20) cm-' for %I) is reported on the basis of a measurement in a supersonic free jet. The rotational and vibrational cooling in the jet is evaluated from the spectra of vi and vq and their hot bands. Rotational temperatures are 32 k 7 K and vibrational temperatures of the hot band (vi +v+,) -vg about 240+ 30 K. The results are important in relation to IR laser chemistry and to modelling the absorption of freons in the atmospheric window.
