Abstract:

A virial equation of state was applied to oxygen spectroscopic measurements at 1270 nm band. Second virial coefficients were evaluated from data analysis of compression factor as a power series in molar density and pressure. Similar virial expansion was applied to integrated absorption intensity (integrated absorbance); Voigt full width at half-maximum height (Voigt FWHM); also; as a power series in molar density and pressure. Some semi empirical formulae have been investigated; and some physical constants were calculated.
