Fourier transform spectroscopy was utilized to record absorption line shapes for rotational transitions in the magnetic dipole allowed b1Σg+←X3Σg- system of O2. Broadening coefficients were determined for 42 rotational transitions in the (0,0) vibrational band spanning the spectral range from 13020 cm-1 to 13170 cm-1. Voigt profiles were fit to the experimental line shapes using a nonlinear least-squares technique, and the Lorentzian half-width at half-maximum values were determined as a function of bath gas pressure. The pressure broadening coefficients for O2 by O2, CO, N2, CO2, and SF6 were obtained with uncertainties of less than 5% and the values showed a significant dependence on rotational quantum number. These rotational level dependencies were modeled using both angular momentum and energy-based rotational energy transfer fitting laws. The authors found both the ECS-P and the EPGL-O fitting laws adequately represented the line broadening cross sections.
