Infrared line positions, linestrengths, and pressure-broadening coefficients are required to determine absolute trace gas concentrations from high-resolution absorption spectra. We have measured these values for the infrared absorption lines in the ν 12 band (antisymmetric wag) of hydrazine between

We have measured absolute line intensities in the 2 fundamental band at 1238 cm Ϫ1 of both isotopomers of hypochlorous acid, HOCl. To obtain the partial pressure of the species in the sample mixture, unavailable through direct measurement since HOCl exists only in equilibrium with H 2 O and Cl 2 O a
FIG. 6. Plot of integrated absorption from 965.4774 to 965.6633 cm -1 versus hydrazine column density (number density times path length). The slope is the integrated line strength for this spectral region.
