Self-broadening and carbon-dioxide broadening of lines of the Н$_{2}$S 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$_2$ 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.
