“…At frequencies removed from line center, the Lorentz line shape does not in general give an accurate representation of the true line shape. Long, et al [12] found that water vapor window absorption between 5 and 6 microns could be more accurately predicted by a line shape having more absorption in the wings than the Lorentz profile. Also Benedict, et al [13] found that for the fundamental band of CO the absorption in the wings of lines was less than predicted by the Lorentz shape.…”

Conversion of (atm-cmL-j-p to molecules cm' 2 [16] The molecular weight, M, of any gas in grams occupies 22.4136 liters at STP [12] so one cm3 of any gas at STP weighs atm-cnu-j-p = 3.5938x10 where r is the mixing ratio and P is the total pressure in torr.…”

The experimental results obtained in this study were compared with calculations made from the AFCRL line compilation. The theoretical background for making such calculations is thoroughly discussed, and listings ot two computer programs written to perform the calculations are presented. The calculated values for the NjO absorption coefficients agree very well with the experimentally measured absorption cofficients. For other gases the agreement between calculation and measurement is not as good, although in most cases the calculated absorption coefficients are of the same order of magnitude as the experimentally measured results.
