摘要

Voigt deconvolution method was applied to analyze experimental pure oxygen absorption spectrum at 1270 nm band. This method gives two bands, the first is a weak discrete absorption band at 1268 nm and vanishes under high pressures, whereas the second is a continuous absorption band at 1264 nm and prevails under high pressures. Applicable pressures were varied between 10 and 25 bar, and temperatures at 298, 323, 348, and 373 K. Competition between pressure broadening and Doppler broadening was very sensitive. Gaussian width, Lorentzian width, and Voigt full width at half-maximum height (Voigt FWHM) were calculated for each spectral line.
