Air-Broadening and Shift Coefficients of O3 Lines in the nu2 Band and Their Temperature Dependence
Room temperature measurements of self- and air-broadening coefficients are reported for over 370 transitions covering a range of 0 </= J" </= 45 and 1 </= Ka" </= 12 for the nu2 ozone band in the 630 to 800 cm-1 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 O3 absorption spectra (0.005-cm-1 resolution) recorded at various temperatures (29 to -63&deg;C) 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 nu1 band. Copyright 1997Academic Press
