The rotational structure of the ν2 band of CF 3Cl, with natural isotopic abundance, has been investigated using a tunable diode laser spectrometer. The spectra have been obtained for a low-temperature (⋍200 K) sample, to reduce the interfering contributions of hot-band transitions. Due to the very small value of the (∆ A - ∆ B) constant for both isotopic species, the K structure of most P( J) and R( J) multiplets is generally not resolvable. Only for CF 335Cl, the K structure could be resolved for P( J) multiplets with J≥55. Molecular constants for the ν2 fundamental of both isotopic species have been obtained using least-squares fitting routines in combination with band contour simulations for unresolved K structure.
