The spectra cover the $600-2700 cm^{-1}$ region at $0.005 cm^{-1}$ resolution. Broadening gas pressures varied from approximately 100 to 250 Torr. Using a multispectrum nonlinear least-squares $procedure^{1-2}$, we fit 29 of these spectra simultaneously to determine the air-broadening and shift coefficients and their temperature dependences for nearly 550 lines in the $\nu_{1}$, band. Self-broadening coefficients were also determined. These results cover a wide range of rotational quantum numbers, particularly in the {R} branch, with $J^{\prime\prime} \leq 55$ and $K_{a}{^{\prime\prime}} \leq 12$. The variation of the retrieved broadening and shift parameters with the rotational quantum numbers has been examined; particularly interesting behavior is noted as the value of $K_{a^{\prime\prime}}$ approaches that of $J^{\prime}$. The broadening and Shift results compare well with previous room-temperature measurements in the $\nu_{1}$, band, and they are also consistent (within the stared uncertainties) with the few previous measurements of the temperature dependence of air-, $N_{2}$-and $O_{2}$-broadening coefficients in other $O_{3}$ bands. Results in the $\nu_{2}$ band have recently been obtained (see the following paper), and analysis of lines in the $\nu_{1}+\nu_{3}$ band is progress. en_US dc.format.extent 152804 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title TEMPERATURE DEPENDENCE OF AIR-BROADENING AND SHIFT COEFFICIENTS OF $O_{3}$ LINES IN THE $\nu_{1}$ BAND en_US dc.type article en_US
