Self-Broadening and Carbon-Dioxide Broadening of Lines of the H2S Molecule

Carbon-dioxide-broadening coefficients and self-broadening coefficients of lines of the main isotopic modification of Н 2 S are estimated on the basis of literature data. The J ′-dependences of the above line-profile parameters of the hydrogen-sulfide molecule are examined. In the case of CO 2 broad...

Description
Summary:Carbon-dioxide-broadening coefficients and self-broadening coefficients of lines of the main isotopic modification of Н 2 S are estimated on the basis of literature data. The J ′-dependences of the above line-profile parameters of the hydrogen-sulfide molecule are examined. In the case of CO 2 broadening, the half-widths of lines are calculated by a semiempirical method based on a parametric modification of the impact semiclassical model; the model parameters were determined from the fit to experimental data.
