Abstrakt:	Using a Bruker IFS 125 HR Fourier spectrometer, the high-resolution spectrum of the 16O35Cl16O molecule is recorded in the region of the band, in which more than 2000 transitions with the maximum quantum numbers Nmax = 59 and = 16 are identified. The obtained experimental data are analyzed based on the model from the work [Phys. Chem. Chem. Phys. 23 (8), 4580–4596 (2021)], which takes into account the existence of spin-rotational interactions in the molecule. The root-mean-square deviation of rotational–vibrational energies from the calculated values for the (101) state was = 2.5 × 10–4 cm–1, which is 35 times better than the data known from the literature.
