“…The complicated nature of atmospheric molecular absorption has been discussed in detail in a previous report [1]. In that report, the major individual molecular absorption contributions in the DF region have been computed, and the molecular line, wing, and continuum absorption mechanisms which account for DF laser molecular absorption have been described.…”

“…Those differences which, under all the conditijns considered here, cause less than a 20% change in the total molecular line absorption have not been incorporated. The original sea level contributions of various molecules to the line absorption of P, (9) were given in our earlier report [1]. These are compared with the revised values in Table 1.…”

^ IThis report has been reviewed by the RADC Information Office (01) and is releasable to the National Technical Information Service (NTIS). At NTIS it will be relersable to the general public including foreign nations. This report has been reviewed and is approved for publication. 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%,

“…Other measurements by Burch [29] are more widely used, having been employed by Spencer [32), Long [33] and Meredith [34] in their modeling. Burch's measurements are in general agreement with the Lowtran values (Lowtran is only about 20% less absorbing at 4 j im).…”
