AIR-BROADENING AND SHIFT COEFFICIENTS OF O-3 LINES IN THE NU(2) 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 less than or equal to J '' less than or equal to 45 and 1 less than or equal to K-a '' less than or equal to 12 for the nu(2) ozone band in the 630 t o 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 O-3 a bsorption spectra (0.005-cm(-1) resolution) recorded at various temper atures (29 to -63 degrees C) with a Fourier transform spectrometer wer e used in the analysis. The spectral line parameters were deduced by a nalyzing all of the 29 spectra simultaneously using a nonlinear least- squares fitting technique. The results are compared with similar measu rements obtained in the ozone nu(1) band. (C) 1997 Academic Press.
