Abstract The infrared spectrum of FCl18O3 has been recorded in the 610-1170 cm−1 range, using a Fourier transform spectrometer with a resolution of 0.0024 cm−1. The ν1 and ν2 parallel bands (with bandcenters at 1011.107 and 708.235 cm−1 for the (F35Cl18O3 isotopomer and 1007.483 and 699.330 cm−1 for the (F37Cl18O3) isotopomer) have been studied and their resolved J and K structures have been analyzed. A set of accurate molecular constants has been determined for the ground and v1 = 1 and v2 = 1 excited states of both isotopic species which reproduce ca. 9700 observed lines with a standard deviation of ≈ 1 × 10−4 cm−1. No perturbation was found at the present level of accuracy. A r0 structure of FClO3 has been deduced.
