STUDY ON INFRARED SPECTRA OF CDF₃ EXCITED STATES

Vibrationally excited spectra of CDF₃ have been studied with a CO₂ laser and FTIR spectrometer. Seven difference bands are observed in the experiment. The anharmonic constants determined from these bands agree with the calculated result by Kirk et al. according to its isotopic species CHF₃ J. Mol. Spectrosc. 58(1975)102.
