Absolute intensities and pressure-broadening coefficients for several individual vibrtion-rotation lines in selected spectral intervals in the $\nu 1$ band of ozone were determined from laboratory spectra recorded in the $1100-1150cm-1$ region with a tunable diode laser spectrometer system. Ozone was prepared from $99.98\%16O$-enriched oxygen samples by the silent electrical discharge technique. Air and nitrogen were used as the broadening gases. Self- and oxygen-broadened halfwidths were also detemined for a few transitions. In addiction, air- and nitrogen-broadened halfwidths at room temperature for a number of lines in the same band were determined from spectra at $0.005-cm-1$ resolution recorded with the Fourier transform spectrometer system at the National Solar Observatory on Kitt Peak.
