چکیده
|
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.
