Using a Bruker IFS 125 HR Fourier spectrometer, the high-resolution spectrum of $^{16}$O$^{35}$\text{Cl}$^{16}$O molecule was recorded in the region of the $\nu_1+\nu_3$ band, in in which more than 2000 transitions with maximum values \textit{N}$^{max}$=59 and \textit{K}$^{max}_a$ = 16 were interpreted. The analysis of the obtained experimental information was performed on the basis of the model from ( Phys. Chem. Chem. Phys. 2021. V. 23. N. 8. P. 4580--4596) which takes into account the presence of spin-rotation interactions in the molecule. The standard deviation was $d_{rms}$ = 2.5 $\cdot 10^{-4} \text{cm}^{-1}$ and is 35 times higher than the result known in the literature.
