【 摘 要 】

A variety of phenomenological line-shape models are compared with a speed-dependent Blackmore profile describing an O2spectral line. Multispectrum fitting techniques and quality of the fit parameter were used to quantify this comparison. It allowed to indicate which models are adequate for analysis of spectra measured with a given signal to noise ratio. This research has an impact on interpretation of spectral analysis results, improvement of spectroscopic databases, atmospheric remote sensing, trace gas metrology, and Doppler thermometry.
