Abstract

Spectral-emissivity measurements of the 4.3-μ CO₂ band were made at high temperatures. Under the conditions of the present experiments, the fine structure in the 4.3-μ CO₂ spectrum is smeared out and comparable with a weak-line band model. A comparison of the observed spectral emissivities with theoretical band-model calculations shows good agreement. The measured integrated intensity of the 4.3-μ CO₂ band between 2650° and 3000°K is 2850 (cm⁻¹/cm at STP) and agrees well with measured room-temperature values.
