We have recorded high-resolution Fourier transform absorption spectra
of ozone broadened by dry air, by N2, or by O2 at room temperature. Fr
om these spectra we have determined pressure-broadening and line-shift
coefficients for over 270 lines in the nu1 + nu2 + nu3 and 3nu3 bands
. The Lorentz broadening coefficients obtained in these bands are simi
lar to those determined from measurements in the nu1, nu3, and nu1 + n
u3 bands. However, there is some evidence for a small vibrational depe
ndence of the broadening coefficients. As expected, the pressure-induc
ed lineshifts determined in the 3-mum hands are significantly larger t
han those observed in the 4.8- and 9-mum regions. (C) 1994 Academic Pr
