We have recorded a series of high-resolution absorption spectra of ozone broadened by dry air, by $N2$, and by $O2$ at room temperature using the McMath Fourier transform spectrometer at the National Solar Observatory on Kitt Peak. The spectra cover a wavenumber range from approximately $2600cm-1$ to $3600cm-1$ at a resolution of $0.01cm-1$. Using recently-determined line positions, assignments, and $intensities1,2$, we have analyzed these spectra to determine pressure broadening and line shift coefficients for a number of lines in the $\nu 1+\nu 2+\nu 3$ and $3\nu 3$, band systems.
