The authors have recorded high-resolution Fourier transform absorption spectra of ozone broadened by dry air, by N[sub 2], or by O[sub 2] at room temperature. From these spectra they have determined pressure-broadening and line-shift coefficients for over 270 lines in the [nu][sub 1] + [nu][sub 2] + [nu][sub 3] and 3[nu][sub 3] bands. The Lorentz broadening coefficients obtained in these bands are similar to those determined from measurements in the [nu][sub 1], [nu][sub 3], and [nu][sub 1]+[nu][sub 3] bands. However, there is some evidence for a small vibrational dependence of the broadening coefficients. As expected, the pressure-induced lineshifts determined in the 3-[mu]m bands are significantly larger than those observed in the 4.8- and 9-[mu]m regions.
