Abstract
The Lorentz line shape formula is applied in the determination of half-width parameters due to foreign gas broadening. Various pressures of SO2 and CO2 are added to HCl and CO, respectively. The (1–0) and (2–0) HCl bands, as well as the (2–0) CO band, are investigated, and there is found to be a very definite relationship between the half-width and the rotational quantum number, J. No error of more than 5 percent should be expected for the values of γ0 presented. Some pressure-shifts are observed for HCl, but no quantitative determinations are made.Keywords
