Multispectrum analysis of pressure broadening and pressure shift coefficients in the and laser bands

摘要: Abstract Extensive high-resolution experimental determination is provided for air- and N2-broadening pressure shift coefficients the two 13 C 16 O 2 laser bands (located at 913.4 1017.6 cm −1 , respectively), in addition to new measurements of self-broadening self-shift 12 bands. These parameters were determined from analysis spectra recorded with McMath–Pierce Fourier transform spectrometer (FTS) National Solar Observatory on Kitt Peak, Arizona. We used a multispectrum nonlinear least-squares fitting technique analyze 30 long path, room temperature absorption spectra. By combining CO same fit we able obtain consistent set line both molecules. The results obtained compared each other, values HITRAN database, reported literature CO2 Comparisons revealed no significant differences broadening or between isotopomers agreed closely.
