Oxygen-broadened linewidths have been measured at room temperature using a method of laser spectroscopy. By combining these parameters with previously measured nitrogen-broadening values, air-broadening parameters have been derived. The averaged experimental data for self-, N2, and O2 broadening have been compared to theoretical values calculated on the basis of an improved semiclassical model previously used for N2O. Quite satisfactory agreement is observed up to J ≃ 50.
