✦ Synopsis

High-resolution (⌬ ϭ 2.3 and 2.9 ϫ 10 Ϫ3 cm Ϫ1 ) FTIR spectra of natural and 35 Cl monoisotopic CH 3 CF 2 Cl have been recorded at Ϫ70°C in the 600 -1400 cm Ϫ1 range. The bands 7 , 8 , and 15 have been rotationally analyzed for both isotopic varieties. With the help of predictions based on 8 parameters, the millimeter-wave spectrum of the 35 Cl species in the v 8 ϭ 1 state has been observed and jointly fitted with the IR data. Only a small number of local perturbations have been detected in the spectra. Altogether more than 8000 IR transitions have been fitted with an experimental precision of ca. 3 ϫ 10 Ϫ4 cm Ϫ1 .
