Abstract

The infrared spectrum of natural CF2Cl2 has been investigated in the ν1 band region at a resolution of ∼0.002 cm−1 using a tunable diode laser spectrometer. The measurements have been carried out at low temperature (∼200 K) in order to deplete the “hot band” contributions; nevertheless, the spectra still exhibit an extremely high density of lines due to the presence of different chlorine isotopic features. Many P- and R-branch transitions of the CF235Cl2ν1 band covering J and Ka values up to 45 and 9, respectively, have been identified. The band was found to be perturbed by Coriolis-type resonance and at least two nearby states, ν8 and ν2 + ν7, seem to be involved in the interaction. From the assigned transitions a set of effective constants for the ν1 fundamental of CF235Cl2 has been derived.
