摘要: Abstract To improve the fit of spectroscopic parameters recorded by Fourier transform spectrometer (intensities, broadening coefficients, and pressure shift), we have developed a multispectrum fitting technique, this technique being already described other research groups (Benner DC, Rinsland CP, Malathy Devi V, Smith MAH, Atkins D. JQSRT 1995;53:705; Carlotti, Appl Opt 1988;27:3250). We describe algorithm software allowing to analyse visualise several spectra simultaneously. validate our software, line intensities (for N 2 O CH 3 D) self-broadening coefficients were fitted compared with previous studies. also studied wave numbers them heterodyne measurements in order estimate relative accuracy results.
