Extended high temperature measurements of absorption at 104 μm in CO_2

Measurements of absorption by the P(14)-P(24) 10.4-microm CO(2) laser transitions have been performed at 200 Torr at temperatures from 540 to 775 K. Using these results plus earlier data, empirical curves describing the absorption coefficients as a function of temperature are determined over the temperature range from 295 to 775 K. Comparison of model predictions with experiment is made and a discussion of the divergence between them is given.
