title: High temperature 10.4-microm absorption in CO(2)-He-N(2) mixtures.
abstract: Absorption coefficient measurements in CO(2)-He-N(2) mixtures have been performed over the 295-650-K temperature range at four wavelengths of the 10.4-microm CO(2) laser transition. Calculated values of the absorption coefficient were compared with the measured values for fifteen gas mixtures and agreed to >10%. A gas mixture interpolation scheme allows an accurate estimation of absorption by gas mixtures other than those on which measurements were made. A less accurate but simpler interpolation method, dependent only on the fraction of C0(2), is also discussed for determining the absorption coefficient.
