This paper presents the results of the measurements of absolute values of absorption coefficients of the CF 2Cl 2 molecule in the regions 915–915.7 ( P branch), 923–923.5 ( Q branch), and 929.55–930.10 cm −1 ( R branch) carried out using a diode laser spectrometer with high resolution (10 −4–10 −3 cm −1), and vibration-rotation transitions have been identified in these ranges. The integrated intensity of the ν 6 band CF 2 35Cl 2 s = 292 cm −2 atm −1 and the first derivative of the dipole moment ∥ ϖμ ϖq 6 ∥ = 0.38 D have been found.
