The air-broadened spectra of N2O, HDO, and CH^ have been measured in the DF laser region between 2545 cm~l and 2745 cm -l. These measurements were performed at a resolution better than the individual absorption line V7idths. The measured spectra are compared with synthetic spectra calculated using the AFCRL Atmospheric Absorption Line Parameters Compilation. For N2O, excellent agreement is found between the measured and calculated spectra. The measured HDO lines tend to be stronger and wider than calculated, by factors of 50% and 25%,

A computer procedure for determining molecular absorption line parameters is described. Techniques are included in this procedure which overcome many of the difficulties associated with obtaining strength and width parameters for overlapped lines of atmospheric gasses.
