Line broadening, shifting and mixing parameters of OCS perturbed by O2 in the ν3 + ν2 − ν2 and 5ν2 − ν2 bands

► With Fourier transform spectrometer, infrared absorption spectra of OCS gas sample were recorded. ► We have measured O2 line mixing, broadening and shifting parameters. ► We have calculated the broadening parameters using a semi-classical model.
