✦ Synopsis

Room temperature measurements of self-and air-broadening coefficients are reported for over 370 transitions covering a range of 0 £ JЉ £ 45 and 1 £ KЉ a £ 12 for the n 2 ozone band in the 630 to 800 cm 01 spectral region. In addition, the temperature dependence of air-broadened halfwidth and air-induced pressure shift coefficients have been determined for over 350 spectral lines. A total of 29 O 3 absorption spectra (0.005-cm 01 resolution) recorded at various temperatures (29 to 063ЊC ) with a Fourier transform spectrometer were used in the analysis. The spectral line parameters were deduced by analyzing all of the 29 spectra simultaneously using a nonlinear least-squares fitting technique. The results are compared with similar measurements obtained in the ozone n 1 band.
