Measurements of air-broadened and nitrogen-broadened half-widths and shifts of ozone lines near 9 μm

Air- and nitrogen-broadened half-widths and line shifts at room temperature for more than 60 individual vibration–rotation transitions in the ν1 fundamental band of 16O3 and several transitions in the ν3 band were determined from infrared absorption spectra. These spectra were recorded at 0.005-cm−1 resolution with a Fourier-transform spectrometer. A tunable-diode-laser spectrometer operating in the 1090–1150-cm−1 region was also used to record data on oxygen-, nitrogen-, and air-broadened half-widths for selected individual transitions. The nitrogen- and air-broadened half-widths determined by these two different measurement techniques are consistent to within 4%. The results are in good agreement with other published measurements and calculations.
