Spectrosc., in press (1990).Author Institution: Atmospheric Sciences Division, Mall stop 401A, NASA Langley Research Center; Physics Department, College of William and Mary; Atmospheric Sciences Division, Mail stop 401A, NASA Langley Research CenterWe have recorded a series of high-resolution absorption spectra of ozone broadened by dry air, by $N_{2}$, and by $O_{2}$ 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 $2600 cm^{-1}$ to $3600 cm^{-1}$ at a resolution of $0.01 cm^{-1}$. Using recently-determined line positions, assignments, and $intensities^{1, 2}$, 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
