H2S absorption in the 3.6–4-μm wavelength region is studied with a tunable diode laser spectrometer. Wavelengths, line strengths, and pressure broadening coefficients of the strongest lines and of the lines adjacent to deuterium fluoride (DF) lines are determined. With these data the absorption cross sections of H2S at 1P DF wavelengths are calculated for atmospheric conditions and compared with the absorption cross sections measured directly with a DF laser.
